The biggest and most common financial regrets people will have.
1. "I should have started investing and making financial plans, earlier."
2. "I wish I had taken more risks and tried more things, when I was younger."
I think regret will be experienced by all people even if it can be said to be successful in general. Suppose you ever heard this sentence from a rich guy, "I should've invested all my wealth in bitcoin 10yrs ago instead of just a few cents, maybe I'd be in the top 100 of the richest ppl in the world."
I believe that everyone has their own lifeline. To reduce the feeling of regret, "be grateful for yourself today".
