Keep playing. As much as you can. Play, post, ponder. Rinse and repeat. You probably just aren't good enough to consistently win yet, I know I'm not. Give it time. You'll get there. 100BB could just be a fluctuation, but you should probably just worry about improving. If you start to sweat your bankroll, think about getting a job (if you don't already have one). Playing less than 2/4 for anything other than bonuses is incredibly difficult long-term.
