...i know what you mean. i'm still at uni, but, i've always wondered what would happen after it. i've always wondered what id do with myself. a downfall to the education system, is that, it's all we've ever known. we get addicted to the lifestyle. it becomes a painful, isolating (as we see our friends we have known for years, jusst drop off to chase other quests), addictive drug. after it, we feel sort of... empty. useless. unfulfilled with our lives.
for now (until i can get a better answer myself); i'd just say: to keep chasing. don't get comfortable. don't allow yourself that luxury. you've graduated? good. now see if you can obtain a masters. you have a masters? good now see if it would be worth it to obtain a phd. if not, get back to uni and study another degree that you would be interested in taking to that phd level. don't settle for mediocre.
