Intelligence VS Dilligence

While the rest of the guys are having fun with Texas Holdem n beer next door on a Friday night, I am mugging away alone in the apartment. I am trying very hard to catch up, struggling to cramp all that were taught in class in my puny brain.

I've tried real hard making conscientious efforts to be super attentive during lessons, but somehow my brain just wondered around after every few minutes. Is it because I have aged, or is it because my brain is half dead? Maybe the lessons are just too intellectual for me, thus I feel too lost to even be able to concentrate. Sigh...
