Ideas for the Future?? (My general Passions)

Art, music, gaming, streaming, writing. If I could do these all at once, I think I would be in my happiest space, but that isn't realistic is it? I want to start a band and write a book as well as stream my favourite games and be a paid artist.

Thats so many things and there are even more things I just like so, what do you really do when you have this many ideas and things you like? Do you only stick with one and hope it gets you far and makes you happy or do you try all of them?
