Update: I wrote this long ago, and since then, I have come to terms and even begun to appreciate being a generalist. There's a wonderful book called Range: Why Generalists Triumph in a Specialized World that explains the value in having a breadth of knowledge even in an increasingly specialized world.

In a lot of circumstances, it can be useful to have a wide breadth of knowledge: that is, to know a little about a lot of things.  It's useful in my job, where I am the System Administrator/DBA/developer/etc.

That being said, I feel like I need to increase my depth of knowledge in one or more areas in order to be more useful to the Open Source and Ubuntu communities.  I feel as though my contributions are not as significant as I'd like them to be, but I'm also not sure in which direction to take them.

So how can someone who knows a little about a lot learn a lot about a little to be more useful in the community?
