I hate talking about financial success because I don't want to discourage the young, who are mostly doing better than they realize. I have a 26-year-old who, unlike many his age (myself included at that time), wants to learn from the fiscally responsible people around him. My advice to him is simple: max out 401k, stay 100% in S&P 500 for the next couple decades, and think very carefully about long-term commitments (marriage, kids, major loans).
I am four years away from early retirement myself. I also continue to save aggressively, but the real driver of my portfolio is the compounding growth over the last 30 years. Now, for better or worse, our investment swings are often greater than our total yearly paychecks combined. We are debt-free at this time and on track to pay off our new home before we retire. We don’t have any kids so we’ve always spent money on travel and luxury cars, which I pay cash for. We’ve been able to live off the rest of our income worry-free by prioritizing our career growth and retirement savings above all else.
