I don't know If I understand exactly what you are asking. We have a lot of decisions to make when we are playing poker, and we can play with more aggression, or passive.
When you play with aggression you take the decisions, you will lead the game actions, your opponents will need to play with caution, or try to be more aggressive.
When you think about play more passive, you need to take a lot of things in mind, first you will not be passive all the time, and any aggression can be read by the villains, and with can help you a lot, using a solid image to steal and bluff.
I usually don't will fold AA preflop, except when I'm in a satelite tournament, and have enough chips to win, cause calling with AA against many players can make me lose, sometimes you can just sitout and wait to the finish.
Stealing the blinds will be good for you, you will need to make this in the tournament, but when someone make a lot of this against you, you can use a close range to defend your blinds. Some players just goes allin to steal the blinds, when they are on the HJ, BT or SB, you can call with a good hand, but with careful, some players know that you can call, and will shove the top of their range too.
