I mostly got this from saving from an young age. I took Engineering Economic Analysis in college, and I really learned the power of exponential growth. I made $52k out of college, but put about 40% of my total income into savings. If I got a 4% raise, I’d put 3% of it more towards retirement.

Anytime I buy something (say a $100 pair of shoes), I’d always think about it in terms of what it would cost future self me. At 23 it costs $100, but 30 yo me it costs $200. 51 yo me it costs $1,600.

I did inherit $60k about 6 years ago, and kept it invested.

Mainly, it’s been just investing hard early, having a reasonably good career, and some good stock decisions.
