Self-made millionaire very early retired people share most significant cash is sorry for

“The one thing I really wish I did more of was saving, and especially investing more aggressively,” he says. “It’s exponential growth. The longer you invest, the more money you’ll have at retirement. Period.”

Adcock says he did the “bare minimum” when it came to saving in his early 20s.

“I was saving 10%, which is the commonly recommended saving/investing percentage of your income,” he says. “So at least I was doing that.”

What Adcock describes as the minimum is a very reasonable starting point for many savers. But if you want to build the kind of portfolio that will allow you to retire early, you’ll have to invest as much as possible, as early as possible.

Early in his career, Trias monitored his investments obsessively, a habit he now views as a drain on his mental energy.

“My greatest regret financially wasn’t my spending, it was my thinking,” Trias says. “I used to think all the time about investing at a low price, waiting and then selling at a higher price. I cannot begin to explain the anxiety and waste this sort of mental framework caused.”

Eventually, Trias learned that it was better for his mental health — and the health of his investments — to avoid trying to time the market.

“One of the things that works really well is an almost mindless habit of repetitiously saving and investing every [time] you get your paycheck, irrespective of what might be happening in the world economy or whether you think stocks are overvalued,” he says.

In doing so, you’d be employing an investing practice known as dollar-cost averaging. By investing the same amount at regular intervals, you not only resist the impulse to react emotionally to the market, but you also virtually guarantee that you buy more shares when the prices are low and fewer when they’re high.

“Looking back, I could have stayed for at least another year and found a new role within the firm in a different office,” he says. “I had always wanted to work overseas — someplace in Hong Kong, Taiwan, Beijing or London.”

Sticking around also would have allowed him to bank even more money for retirement.

“I would also put 100% of the extra money earned into various risk assets like stocks and bonds. Assuming a 4% annual return, I could have generated an additional $20,000 or more in passive income per year,” he says.

Instead, he left and negotiated a severance package in exchange for onboarding his replacement — not a terrible consolation prize. He even managed to burn a few vacation days before his departure.
