You seem to doing fine, but dont get all turned up side down if things turn around, and poker bites you on the butt It happens, it always happens... Its to early to know yet if you are a winning player, but even if you are or not, there is no doubt that almost anyone can become a winning playet. Just pratice all the time, and try hard to never, never, NEVER tilt. The latter is maybe impossible But always try to keep your head up. I think you should stick to 10NL, just let your roll grow and don't step up to 25NL until you have at least 250$ or so. Moving down to 2NL is imho not a good idea. Bankroll management is important, but I don't think its so friggin' important at micro stakes. If you lose 20 bucks I surely think you can scrape op another two-three buy-ins if needed? If not I think you should reconsider playing poker, and make take it up when your private finances is at better shape.
