Live MTT strategy with only 3k starting chips

I've got a live tournament tomorrow that I'm not as confident about as usual, as the starting stack is only 3k with blinds starting at 25-50. I'm used to starting with 8-10k, however, it is possible that players will not be raising as hard in the first few levels because of this, so I may not have to adjust my game much. But I am wondering if there is anything you might do to try and level your game with so few starting chips. The levels are 20 minutes btw.
