Hehehe... quite important for me. lol
I remember reading this waaaaay back before I started on this crazy grad school thing. It was good advice then, and it's still good advice now. Especially the part about the "slump" that happens at about the halfway point... although when I hit that point, I'll admit, it was really hard to tell if it was just a slump or a genuine desire to quit. When everyone else you know is employed, has an actual income, and a REAL life, it's pretty tempting to throw in the towel and forget about finishing.
Very tempting indeed...
Not that I'm thinking about that right now. Of course not. :P
