Tight aggressive is a good style. I agree with others, you do need to throw some chips around on occassion when dealt less than great cards. Mix it up a little, not too much.
There are many ways to handling a player trying to run over you. Reraise and calling are options to slow them down.
I like it when a table is down to 4-5 players, everyone folds to the blinds and the small blind decides they are going to raise me. If I have junk I simply fold maybe 2-3 times. When the blinds increase and they try again, I reraise (cards do not matter, I am playing the player), they fold and I get more in one pot then the other 2-3 times when I folded. Of course if I re-raise with junk, I am still ready to fold to a big shove.
Mix it up but stick with the tight aggressive style blended with some loose well read plays.
Later,
