Would you really going feel that much better if your ventures had “succeeded” (whatever that means). Odds are if you were rich you would wish you were richer. If you were powerful you’d wish you were more powerful.

You can learn to accept that what you’ve got is what you’ve got and that fundamentally none of it matters.

Personally, I have no dreams and no goals and I get by just fine. Just passing time until I die and it’s not awful. There’s nothing wrong with mediocrity. Most people are mediocre (me included).
