Your 40s often feel like the balancing act decade: you’re experienced enough to know better, but still energetic enough to think you have time to catch up later. You might be juggling a demanding career, raising kids, helping aging parents, and trying to carve out some sense of personal time in between. It’s a decade of momentum—yet also one where the habits you set will shape the rest of your life.
Ask baby boomers now in their 60s or 70s what they regret most, and you’ll hear a recurring theme: “I thought I had more time.” They assumed they could delay certain decisions until their 50s or retirement, only to discover that the 40s were the last real window to build the foundation for health, wealth, and happiness later.
The good news? If you’re in your 40s now, you still have time to avoid these regrets. Here are the 10 most common things boomers wish they had done differently in their 40s and why these lessons matter more than ever today.
1. Not Saving Aggressively for Retirement
Boomers frequently cite this as their single biggest financial regret. Many contributed to a 401(k) or pension but assumed that small amounts would be enough over time. What they underestimated was how powerful compounding can be in your 40s, and how difficult it is to “catch up” later.
For every dollar you invest at 40, you could potentially have double or triple that amount by 65, thanks to compound growth. Conversely, every dollar you fail to save now requires multiple dollars later. Unfortunately, many boomers didn’t realize this until their mid-50s, when the pressure of looming retirement left them scrambling.
One boomer summed it up bluntly: “I bought cars instead of maxing my 401(k). Now I drive an old car because I didn’t plan ahead.” If you’re in your 40s, consider increasing contributions whenever you get a raise, eliminating debt aggressively, and diversifying your retirement accounts. The comfort of future-you depends on the discipline of present-you.
2. Not Paying Off the Mortgage Sooner
Carrying a mortgage into retirement is more common than ever, but that doesn’t make it easier. Boomers who failed to pay down housing debt in their 40s often find themselves making payments on a fixed income, limiting flexibility and increasing stress.
For many, this wasn’t due to irresponsibility. It was due to refinancing for home improvements, tuition, or consolidating other debts. But what seemed like a smart move at the time translated into a longer mortgage term and higher overall interest.
Paying off your home before retirement provides more than financial relief. It creates peace of mind during unpredictable economic times. If eliminating your mortgage in your 40s seems unrealistic, at least avoid extending its life unnecessarily.
3. Ignoring Health Screenings and Physical Fitness
Boomers often confess they put health on the back burner in midlife, either out of busyness, denial, or a sense of invincibility. Many skipped routine screenings, avoided annual physicals, and assumed they could “get serious about fitness later.”
The consequence? Chronic conditions like diabetes, high blood pressure, and joint issues crept in silently. By the time they tried to reverse the damage in their 60s, it was harder—sometimes impossible.
Your 40s are the critical decade for preventive care. Regular check-ups, cancer screenings, and exercise aren’t just about looking good. They’re about building a physical foundation that will carry you through retirement. Muscle mass declines sharply after 40, making strength training essential for long-term mobility and independence.
4. Not Creating Multiple Streams of Income
Most boomers grew up in an era of job loyalty and pensions. The idea of diversifying income wasn’t mainstream. Many relied on a single paycheck for decades, assuming it was secure. Then came layoffs, downsizing, and recessions.
Those who didn’t prepare secondary income sources, whether through side hustles, rental properties, or investments, found themselves vulnerable. When the job disappeared, so did their sense of security.
Today, the lesson is clear: income diversification is no longer optional. Even if you love your job, consider creating other financial channels in your 40s. A small side hustle, online business, or real estate investment can grow into a safety net by the time you’re ready to retire, or if life forces you to sooner than planned.
5. Letting Friendships Fade Away
Ask boomers about emotional regrets, and this one surfaces often. Career demands, raising children, and sheer exhaustion meant friendships took a backseat. Many assumed they’d reconnect later, but later never came, or when it did, friends had moved away, grown distant, or passed away.
Social isolation is a silent epidemic among older adults, linked to depression and even cognitive decline. Maintaining friendships in your 40s isn’t just about fun. It’s a protective factor for mental and physical health later in life. Schedule regular calls, plan meet-ups, and make the effort now. Your future self will thank you when those relationships become lifelines in your 70s.
6. Not Traveling More While Healthy
Boomers repeatedly say they postponed big trips for “after retirement.” The result? By the time retirement came, health issues, mobility limitations, or financial constraints made those trips impossible.
Your 40s might feel too busy for travel, but they’re often your healthiest years with a reasonable amount of disposable income. Those dream vacations won’t be easier at 70—take them when you can truly enjoy them. Travel doesn’t have to mean five-star resorts or month-long tours. Even weekend trips can create memories that matter far more than material things.
7. Avoiding Hard Conversations About Aging Parents
Boomers who now care for elderly parents often admit they didn’t have important conversations early enough. Topics like long-term care, power of attorney, healthcare proxies, and living arrangements were avoided out of discomfort.
When emergencies happened, families scrambled under stress, leading to financial strain, legal confusion, and emotional conflict. If your parents are aging, start the conversations now. It’s not morbid. It’s responsible. Planning early ensures their wishes are honored and reduces future chaos for everyone involved.
8. Not Pursuing Passion Projects or Education
Many boomers stayed in jobs they disliked for decades, convinced that passion projects or career pivots were “too risky.” Others shelved hobbies, believing there’d be time after retirement.
For most, that time never came, or when it did, energy and confidence had faded. Today, they urge midlifers to take chances. Whether it’s enrolling in a certificate program, launching a side business, or dusting off a long-forgotten hobby, the 40s are your moment to rediscover purpose. The happiest retirees often have one thing in common: they cultivated interests outside of work long before they left it.
9. Neglecting Mental Health
Boomers grew up in a time when therapy was stigmatized and self-care was often dismissed. They powered through stress, burnout, and midlife crises, only to pay the price later with fractured marriages, health problems, or depression in retirement.
Your 40s can be emotionally demanding. Career plateaus, teenage kids, and aging parents create unique stressors. Ignoring mental health doesn’t make those pressures disappear. It makes them grow silently until they explode. Investing in therapy, mindfulness, or stress management now isn’t indulgence. It’s preventive care for your future self.
10. Failing to Plan an Exit Strategy for Work
Perhaps the most overlooked regret? Not preparing for what life after work will actually look like. Many boomers assumed retirement would be endless leisure. Instead, some faced boredom, depression, or identity crises once the title and office disappeared.
Others never got to retire on their terms. Layoffs, illness, or caregiving responsibilities forced an abrupt exit. Those without a plan, financially or emotionally, struggled to adapt. Your 40s are the perfect time to ask: What will give me purpose after I leave full-time work? Whether it’s volunteering, consulting, or a creative pursuit, planning your next chapter now can prevent feeling lost later.
If you’re in your 40s now, you’re facing challenges boomers never imagined—skyrocketing housing costs, disappearing pensions, longer lifespans, and healthcare uncertainties. That makes these lessons even more critical.
Boomers assumed they had time. Many didn’t. Life is unpredictable. Jobs vanish, health changes, and families shift. What you prioritize today determines your options tomorrow. The 40s aren’t just another stage of adulthood. They’re a pivot point. Financial habits, health choices, and relationships formed now will echo through the decades ahead.
Use Your 40s as a Launchpad, Not a Waiting Room
The recurring message from boomers is simple: don’t wait. Don’t wait to save. Don’t wait to travel. Don’t wait to nurture friendships, protect your health, or chase your passions. Time isn’t an infinite resource, and regret is the most expensive debt of all.
The good news? It’s not too late. Whether you start a side hustle, increase your retirement savings, or schedule that overdue doctor’s visit, every choice you make in your 40s compounds into freedom or constraint later.
If you’re in your 40s now, what’s one decision you’re making to set up your future self for success? And if you’re a boomer, what advice would you give your 40-year-old self?
