Is it possible to find a programming mentor?

I'm no stranger to programming. I've dabbled in just about every language, but have mastered none. I need structure for my learning experience. Programming is just wide open and unless you have a specific project to work on, it feels useless. So I am looking for a person willing to share their learning experience with me or even if you just provide in answer ways to learn programming languages so that they become marketable skills. In other words, I usually don't put many programming languages on my resume because I would probably need a reference book for syntax lookup if I got a job as a programmer.
