I began working in video games well over a decade into my career. I was only capable of doing this after I stopped being a programmer and started being a project manager.
That sounds backwards to quite a few people, I'm sure. I went from a young and hip programmer to a manager and THEN went into one of the geeky industries par excellence. Actually, it's a great idea for your career – making the geeky leap later in life, at certain critical points in your career.
