Party Poker and when to make your Stands

[miracle7s]

I have been playing home games and party poker for about 8 months now I have read the books Super System, Play like the Pros Advanced Hold'em Etc.. however i find that no matter how good my hands seem to be they are always getting busted. i am a tight player and usually only come in with Big hands however my kk is getting busted by A2 and the like and just can't seem to find an amount on raises to get people not to call with these kind of hands so I'm asking people here should a just limp or make small raises with these big hands push it all in or what. Do i need to just see more flops with less cards please help me. I feel like phil hellmuth at these tables because i start going off with these idiots sometimes. I know that i get paid off big sometimes by these fish but a little insight from some food players would be greatly appreciated
