Why Doesn't TAG Work For Me?

[guitarizt]

Whenever I play boring 18/15 poker I find myself getting murdered. I might be lucky to start off the session up a buyin, but then I lose it back and more because it seems like I never make the right decision postflop.

When I loosen up and gamble I get paid off on my big hands so I don't have to worry so much about villain slowplaying a set and whatnot, and the game becomes much easier to play.

I posted this in psychology, but does anyone else have this problem? It's so bad that it's to the point where I have made a promise to myself not to play tag this month. If I find myself getting lazy I'll quit the session.

I wish I could play tag so I could just sit down and play 8 tables for a while and clear bonus + rb but apparently I suck at it.
