What To Learn Next?

I tend to be indecisive when it comes to what i really want. Especially when it deals with what I want to be doing with what I'm passionate about. Technology.

Right now I work for a brand strategy firm doing Technical Consulting which has been a very valuable and challenging learning experience.

But what about the skills i want to develop outside of work but still related to my field that I don't get to tackle at my day job?

Right things i think I CAN learn and learn fairly well are:

Web Stuff
- Flash
- Ruby on Rails

Interface Stuffs
- Cocoa Development (Mac OSX Apps, not the bean)
- .NET Development

Hardware Stuffs
- Electronics and hardware interfacing

But is this what I really want? I have no idea. The web stuffs would be useful, but I already do so much on the web I feel like I need to branch out a little more.

Lately I've been playing around with different UI systems such as the Wii Whiteboard and Multi-touch Interface, but I want to actually build software that can utilize these systems as much as possible.

And hardware wise, i love putting things together with my hands, which is why the most relaxing thing for me to do is to build a computer from scratch.

Uh, sorry this is a random rant.
