Yes, I dipped my toe in recently. Because the market has been a bull over the last few months, I have made money. Yet, I worry that my success gives me false confidence in I know what I'm doing. I also devote time to just watching the numbers. And, like watching twitter, I recognize it's not very healthy or constructive.

My approach is closest to technical analysis, swing trading, and the CANSLIM method: http://en.wikipedia.org/wiki/CANSLIM
