Stars $27, Overpair in a raised pot

[Snarf]

Quick question for those who suck less than me:

Why does calling preflop suck here?

10 10 isn't the greatest raising hand....
Theres no antes.... I guess I might have underestimated the pot. (T550) worth taking by pushing it through....but then only to get called only by JJ+....so I don't see the horribleness of calling and seeing what comes out.

I *DO* think that you should make a decision pre-flop wether or not you have the best hand at that moment....that decision would help you to know to push here or fold here w/no set....

someone explain this to me 'cuz I suck and think calling this PF isn't so bad....
