Most of the time in the $1 Sit and gos you can sit around until you get decent hands, while the remaining players basically shoot themselves, leaving the luckiest donker with a big stack and about 3-4 players remaining. It could take 45 minutes or longer to make it to where you have 4 players remaining. Limp with decent starters in unless you have a very decent pocket pair. Decent PP in hand = play it strong. If you haven't won a hand to this point, which sometimes happens, it's not a big deal other than the fact most of the players will raise your blind and bet on the flop.... steamroll you when given any chance. Playing only very decent hands will give you the ability to sit around and have a decent stack for when the blinds actually get to a point where they're high enough to care about and remaining players should be few.
Slow play early on and try to steal a few.
While you're sitting there picking your nose, make sure you take notice of the players with similar playing style as yourself, for later use.
Later on when you and the remaining opponents have a similar or even decent stack, they'll play scared because of their stack size, they know you're tight, and won't do anything to stealing, even if they know full well your full of b.s., because they feel they have no cards to defend with.
My biggest advice would be not doing anything drastic,
bluffing, or chasing, especially early on. When you've made the money you should know your opponent and be able to know when to A) take your chances if you're the short-stack B) Raise the small stack pre-flop or bet on the flop to folding stations, and even the big stack if your the mid-stack (you want to grind the short-stack down, not allowing yourself to fall into 3rd in chips when the blinds are high) C) Know how and have the ability to take a big-stack donk down heads-up when they have a three or four to one chip advantage, patience and trickery is key imo D) Try not to be bullied too much. Sometimes it's best to put your foot down with an all-in, with a moderately decent starting hand, than to table's hoe. Because the three of you just made the money, and your short-stacked, the opponent will try to grind away at your stack and big blind. The blinds are high and you'll have no choice to push all-in sooner or later, if your short. Don't make it too late. It's better to do this sooner than later, when your stack size is decent enough that there's a chance that you can show them you're not going to take it and there's a possibility they won't call with garbage because your stack is pocket change.
Take your time. I tend to think people take the auto/fast bet as a
bluff more often than not at this level. Sitting for 10 seconds to give them a chance to realize what they have and how you've played previously, which should be with good cards, and tight, they'll think twice about trying to pull-off their favorite

Opponent tendencies, playing patterns, etc, is very easy to see and figure out at the lowest level SNG. Take advantage. Figuring which opponents won't last much longer, because of the amount of hands they play, and playing style is key to your strategy when you're on the bubble.
