Finish...
Seriously, finish what you started, no one is going to look at you once if you have hundreds of ideas that weren't completed.
Start small with simple ideas, perhaps a level of a game or a demo, but make sure that these are the polished finished product (ie the best you can do).
Don't be too much of a perfectist as well, you'll never get things done if you are constantly tweaking.
and finally, don't take up professional wrestling like I did... takes up all your time!
