My Bankroll Isn't Getting Big

I don't really know what it is about my playing that isn't allowing the bankroll to grow. Maybe I am not spending enough time watching tables before I sit down, maybe I'm not playing right, or I might be trying too many SNGs. Not sure, but my bankroll is not where I would have expected it to be right now. I have finally been able to download PokerTracker (not sure what was wrong with my PC, but downloading things lately has been a struggle), and hopefully after I spend some time analyzing what everything means, I will be able to figure out what I have been doing wrong.
