IMO, you can't master one language / instrument/ conceptual framework without a familiarity of several.

To be honest, I just try to build a couple of toy projects in whatever seems useful, and then I will try and build something professionally if I can a) get a client project and b) think its a useful/good fit.

As to the process, you're always better off with 30min a day rather than 2 hours on a Saturday. That's true for most things I've learned.

Specifically, I'd probably try and pick up Javascript, Ruby, or Python, as those seem to be the most portable to me. They also seem to be more widely adopted.
