But at every table there are those people that have no clue what they're doing, they call my ace king with something like three six off, and end up with a staight.
What limits are you playing? If you´re playing at micro limits, the best way to play is just playing premium hands over aggressive. If you´re playing NLHE, your preflop raises should be 5+ x BB. As XD said, you must be very aggressive preflop to punish the maniacs.

I'll bluff and then some times I'll win
Really? Is it profitable to you to bluff at those kind of tables or you lose more than you win?
At microlimits i recommend not to bluff because you´re going to be called.
That´s another reason of playing the extremly tight-extremely aggressive style. You know you´re going to get callers even if you make a huge raise and you have been playing 10% of hands. At those limits the players just play their cards, so you don´t have a table image. They don´t realize that if you´re extremely tight and you come with a raise, probably you have a great hand. You have to take advantage of not having a tight table image, and the best way to do that is raising a lot with monster hands. Of course you can´t prevent bad beats but they will happen less often than the hands you´ll win.
That way of playing is boring and it isn´t good poker. If you play in that way against good players, you´ll become an open book and they´ll fold to your raises making you go blinded out. So it´s important to remember that the extremely tight-extremely aggressive style works at low limits where you don´t have a table image. That style just works to make you win some money at those tables, so don´t stick to that style where you think there are better players.
Another thing to remember: after a bad beat don´t go on tilt. Just keep playing your game and as joshyb said what really matters is that in the long run you will win money.
