The average micro stakes player isn't paying any attention to images. They will pick up on if you are a nutjob player, but they don't notice a tight image. Plus, with many players changing, setting up any image isn't worth it.
For the most part, you will be very profitable just playing tight the whole way. You should never make a 3rd bullet bluff at this level. At worst, you can raise pre, make a c-bet, and on a drawy board that misses, bet again on the turn. After that (or if you are raised) you need to bail. Bulffing again and again at this level is spew, since so many players just can't fold horrible hands, and it only enboldens them to stay in when they call you down and they were right.
You should be making very few fancy plays at this level, and you should have tons of reasons to explain why you pulled that off.
As an excersise, just play a session tight. When you do anything that is even a little loose, you should be able to justify it. Keep notes as you play on why you raised with that hand (it was AA or this player is a good player at this level), and justify why you strayed from being tight. If you are doing it a lot every session, maybe you need to tone it down.
Remember, you can't bluff a bad player.
