Anything below QQ and you are asking to get owned.
Poker pairs outside of AA and KK are, frankly, not very good. Especially not at low limits which most people on this board would play at. Since there are 3-5 people in every hand, and the chances of someone beating that is very high, you will get beat more times than not.
In the long run, you will make more money with AA than any other hand. In the long run, you might lose more money with KK and QQ than any other hand too, at low limits at least. Overplaying pocket pairs is the first mistake people need to weed out.
