I have lots of stuff happening in my head but nothing in my life. How do I change that to lots of stuff happening in both? I don't mind taking a hit and have nothing happening in my head even.
What kind of stuff happens in your head?
What kind of stuff doesn't happen in you life?
You can't get good at anything except through practice. Talk to someone at a pizza parlor.
Maybe you have to spend some time figuring out what it is you want out of life. Try making a short "dreams" list of things you want to have, to do, to be. Be honest, since it does you no good otherwise.
If you can't think of anything, pay attention to how you spend most of your time, what catches your eye, and those idle moments where you have an interesting curiousity about something, but it goes away by the end of the day, or even by the end of the commercial break.
Discover and indulge in your passions -- that could mean playing an instrument, finding and meeting attractive people, travelling, whatever.
Don't hurt the people you care about.
