Oh, and just so you know...it's not reflected in my sig/that thread, but I started out similarly - built up to $200 from a $25 deposit over xmas break, then moved up a level when I wasn't ready. Lost all but $10 of it and then started back on track as best I could from there.

I also have my own unique buy-in system for playing "above my limits" while still playing within my means. Most people don't like it and I get yelled at all the time by people singing the praises of the max buy-in, but I frequently buy-in with the min. amount or close to it. My reasoning is that I think I'm a better player than many people at the levels I can't yet afford, so I play there anyway and buy in with such an amount that I'm still a threat, but not a huge one and I'm not risking too much of my roll. It can work amazingly (like this morning when I turned $20 into $75 in 16 hands), but that requires the perfect table.
