I don't dream or care about things I definitely can't do.

But there are still so many I can actually do that the opportunity cost of choosing any single one of them is infinite, and that leads to paralysis at worst and diluting your self while half-assing dozens of things at best.

Maybe one of them pays the bills, and even a nice house and a decent car. But it's just that, it is not what you really wanted to do, so you keep searching.

The "gift" of being a fast learner becomes a curse. In a few weeks you are an advanced beginner at almost anything. People marvel at how well you are doing, but you know you have just started and can now see how far you are from being any good. But to become good, you'd have to leave behind all the other things, and you can't pick. So you just start a new one for the quick dopamine hits and easy praise...

And then you are 50 and still don't know what you will do when you grow up.
