Going over your games afterwards helps a lot. If you can get your opponent to go over it with you it helps even more. I think you're doing the right thing though - if you work separately on tactics, endgames, openings, and positional play, then you should improve.
I recommend going over some of your games yourself, and giving others to a chess engine to find out which of your moves were less than perfect, and which of the others were outright blunders.
If you have the time for it, then it is best to go over your games afterwards, followed by going over the game with a computer. So, you can write your thoughts yourself, analyzing afterwards and recalling what you were thinking during the game. Then you can see how right you are with the subsequent computer analysis.
A last possibility is to get a chess coach, but I always recommend doing it yourself first.

My rating on FICS tends to fluctuate from 1600-1700. I've been in that range for a pretty long time. I use some books to study with, mainly on tactics and the endgame, and also play on a fairly regular basis against similar strength opponents.
I just can't seem to improve my game anymore, and often times it even seems like I start playing worse. Like currently I'm on a 6 or 7 game loss/draw streak and it seems to work like a snowball effect because I start to play more timid when I keep losing, and opponents seem to sieze on that and play really aggressive and just destroy me.
Recently I've started trying to annotate games I've just lost, and submitting some for analysis and review... but still it seems like my play is just getting worse. Probably going to drop below 1600 soon. It seems like I have plenty weaknesses in every area of the game, because I lose just as spectacularly to opening traps, midgame tactics and endgame oversight.
Can anyone help? I'd like to be able to play consistently in the 1700-1800 range, any advice would be appreciated.
