It's good you've decided to start out with the micro's, dude. Adding another couple of success stories to Jason's, I started at $10 and have $1600~ now, micro2macro started with $50 and is at god knows what, but its at least double me lol, and BooG690 started with $50 too, i believe and is up to $2k+, so it can be done. (Also, we've all done this in under a year, I started in November of 08 and have played VERY little poker since May.)
Good luck, and tear that shit up yo.
