In my experience, I have found that I needed to take a step back and focus on a solid foundation of technical knowledge that is totally language independent. After that, you can go back in and layer in how different languages might help/hinder you in particular situations.

Much of my education was from a "get cool shit done" perspective, and I did. I had solid projects in an array (no pun intended) of languages but lacked some of the true, lower-level knowledge as a foundation.

Your mileage may vary, of course, but if I could start my CS education over again, that would be my advice to... myself..
