From a guy whos gone almost bust multiple times due to bad bankroll management I advise you to play some 2NL on dise untill you get MIN 20X buyins for 10NL. Its not that hard of a grind and pretty easy to double triple or even quaduple your buyin playing solid TAG. If you keep at 10NL I can see you being bust within a day or so if you get a bad run of cards or beats. Play smart and grind that roll up.

Also pokertracker helped me alot and showed me where my big money leaks were and showed me where to improve ( I was playing alot of marginal hands out of position and calling raises with axs with only 1 or 2 ppl in the pot). It might be a good idea to look into it but it costs 3x more than your current bankroll.
