Just submitted all the required forms for the PhD IT program at George Mason University earlier this morning. I have always wanted to pursue it, but never really thought about the challenges behind it until now. All I know is that it is going to be the most rewarding and challenging experience of my life. Anyway, sometimes it is better to not think too much; otherwise, you might get scared and give up without trying. Wish me luck!

Any ideas yet on what your thesis will be about? I know with mine, I had to submit at least a working title if not subject before I was admitted into my program.
Oh yeah. In case you’re not familiar with it, Ph.D. Comics
Good luck,
