I started on ACR with $0 and I've played like 50 freerolls tournaments to get up to the $30 I have now. Now with this $30 I'm playing a tiny bit of .01/.02 cash, and some 0.11 and 0.27 tourneys to balance out my still heavy volume freerolls. The biggest thing with building from 0 is patience, because sometimes you'll play a tournament for 3 hours only to win a dime.
