(has been quoted twice and I needn't quote it again since it's obviously on the nail).
I'm one of the guys who built up several BRs on different sites aswell.
It is definately doable, even nowadays although it was easier before black friday.
I'm currently doing a self challenge in order to get used to grinding
MTTs again (<300MTTs in 2 months challenge) and can say that for me the ulta-micro games still seem beatable.
With that said you have to keep in mind that 10$ really isn't alot and you
could easily go broke even if you don't totally suck.
When playing at MERGE (Carbon) I'd go for the fun-steps sngs
(tickets available at promotions/fun steps) and enter every available freeroll
(format and type of game don't matter) whenever I could.
Also get yourself a trial version of a HUD like holdem-manager or pocker tracker
and enable your hand history settings and save them to your harddrive for further review.
Keep posting here and after some time (I suggest 100 posts) search for and apply for the CC freeroll club.
Those freerolls have a somewhat improved opposition compared to the public freerolls
but the number of participants is much lower and the payout is much bigger.
Don't play real money STTs with less than 25 Bi and MTTs with less than 50 bi.
Good luck and welcome to CC.
