> TBH I also believe in knowing fairly deeply a few areas (you have to have _some_ depth too, not just breadth); There's a specific term for this, it's called "being T-shaped". You have breadth at the top and then depth in one subject area. I think the ideal balance probably varies from person to person. Some people really enjoy going deep on a subject (these are the kinds of people who get PhD's). I personally can't keep my interest on one thing for too long so I end up with a lot of breadth, but I make sure there are a few subjects I revisit a lot so that I manage to build some depth.
