Recently out of college

Hi I'm John, recently graduated from college and looking for a few friends to follow in the younger crowd (18-26)! I've lost weight before (lost 25 lbs last year), but broke my ankle and gained a lot of it back. Now that I am nearly fully recovered, I'm building up my motivation for the long hall of being healthy. I'm also finally out of that hectic college lifestyle of staying up until 2 and waking up early....any words of advice from the recent college graduates? younger crowd?
