Do people really need to be told "Find something that you enjoy doing and then keep doing it"? Really?

I do the things I enjoy, um cause I enjoy them.

I also don't (or try not to) do the things I don't enjoy.

Nobody gave me that stunning advice. It's nature's built in reinforcement loop.

How about; "Do something you suck at (but want not to) or are afraid of. Stick with it at least until you don't suck or are no longer afraid."
