Good that you decided for NL2 and BSS, its the best way to learn (but SSS is better if you just want fast money without too much hassle). As you are a beginner, I would suggest you Use 30BI Rule (Your Total BR divided by 30 = your buy-in) and start adding to your BI's by one dollar as your BR grows. This will stop make you think abou your short term loses as you go down by only small porton of your BR when they happen ( and you are very likely to make plenty mistakes, but thats exactly what you want as you improve with every single one of them!)
Set time for your sessions, e.g. I play 6hours then I quit. And THEN check your br.
This will be impossible for you now, but when you will become a brilliant player you will completely ignore your BR, or just check after a session.
When you lose money don't tell yourself 'Fuck I lost money' Tell yourself
'WoW, I got outplayed or sucked out, how can I avoid this in future?'
Automatically post losing hands where you entered a situations with negative equity (Your chance to win the pot was lower than money you put in the middle relative to the pot) to forums.
If you don't like the hand converter , you can do it like me and post hands to http://www.liquidpoker.net/ and use Pokerstrategy for articles and forums (Just don't go there with Shortstack, you will get crucified).
