I suck, again

This is from an email to a friend:

Yeah I feel you. I can tell you that I didn't make money until I started playing no limit. I keep records of all my poker stuff and I lost in 2/4, 3/6, 4/8 but won a lot in 6/12. I really only lost too huge hands yesterday and that was my undoing: One I had 8d4d and the flop comes Jd10d4c. Then the turn is the 8c, giving me two pair with the flush draw. I bet 150 and the worst player calls. The river is the 2d, giving me the flush. I bet $150 and he calls and has KdQd. Then my last hand the worst player is in early position and raises to $10. I just call with AsKs, then the guy on my left raises to $35. Four people call, making the pot $175. I push all-in for $435. The guy on my left takes a LONG time and then calls. Then the worst player calls. I completely miss the board. I show my hand, the guy on my left has AK also and the worst player won with JJ.

Things that I really pay attention to are how loose/tight every player is, betting patterns/tells on bets, who chases, and who is willing to gamble a lot.
