Money mistakes in your 20's

Hello folks. While I'd like to remain anonymous very much, here's what I can share about myself. 1. Working in consumer finance. 2. Love personal finance and helping people out with it. 3. Have published 10,000+ pieces of financial content in the mainstream media. 4. Wrote a best-selling book on money management. It was No. 1 on Amazon once upon a time. 5. Lately been appearing on TV regularly for personal finance discussions. 6. Saved like crazy through my 20s and 30s, brought two apartments; have an 8-figure net worth mostly thanks to my mutual fund investments. It's not much but it's hard-earned. 7. My unrealised aspiration is travel and I'm working on it now. No, I'm not selling anything. No commissions, no referral links, no finfluencing. Just want to talk, exchange ideas, and learn from you all. Maybe I'll feature you in my next book. :) Ask me anything.

What’s the biggest financial mistake you’ve made in your life so far?

Folks in the age group of 32 and above. What significant change you saw in your life post 30 both in terms of health and work? What do you wish you had done better or a piece of advice for the ones in 20’s. I understand good workouts, healthy eating and financial discipline are top of the list. Would love to get some perspectives beyond that.

What does your Portofolio look like in your 20s. Would also be helpful if you can tell about your health and term insurance.
