Make something. The only way to keep your skills current is to use them, and the best way to expand your skills to to build something.
A great video interview appeared here a while ago. It's about how it takes a couple of years to really get good enough at a creative field to produce good work. You go through a period of creating work that's not as good as your ambition would like it to be. Here's the link: http://www.youtube.com/watch?v=-hidvElQ0xE
It's worth the time to go through the process of creating a body of work. After doing it for a couple years, you'll be able to focus far more on doing something wonderful, rather than just doing /something/.
A recurring theme with these responses seems to be to just go for it and don't worry about messing up because as long as you're learning along the way, you'll be better prepared for whatever the future holds. I think thats terrific advice!
