Illustrated Guide to a Ph.D.
Date: October 5, 2012
I love this.
My professors at FSU were really good at explaining this hyper-narrowing of focus to me, in their own way. Still, I wish I'd seen Matt Might's explaination of the Ph.D. process then (or even better, before I'd left home for graduate school). I'm a bit thick-headed and, despite my professor's best efforts, maybe didn't totally get it until I was deep into the process.
If you are considering going and getting your Ph.D. or D.M.A., check this out. Maybe it will help you understand what you are in for.
