I know exactly how you feel, but seriously like a lot of other players mentioned here, that's poker. You can try playing loose and try to play every single hand, but it'll hurt you in the long run, and not everyone is capable of playing a loose cannon style and gaining chips. The best bet is to learn patience and crack people who play that exact style of playing everything.
Alternately, I also know of many times I think I hit great (ie: 2 pair with 5-8s), but I run into somebody that has trip 5s or trip 8s. ^^
