What do you do when you want to do so much?

I want to learn a language, practice guitar, learn piano, read a book, do some programming, play some games, watch a movie, meet people, watch a show, learn robotics ...

There's too much I want to do. I end up doing a little bit of everything, then feel frustrated by the minuscule progress, if any. I'm stuck in an endless loop.

Anyone in a similar position? Advice?
