I started managing my investments right at the start. I did a lot of active management in the early days, but I stopped for two reasons:
Didn’t have time to actually perform the research necessary to make sound investment decisionsI found managing my own money a lot more stressful than my day job!
I’m mostly passive these days, but I do the odd bit of stock-picking to keep sharp and because it’s fun.
I also bought bitcoin really early, invested like $50, it’s now a few thousand, so I’m a happy camper.
