Advice on playing as the big stack

[skoal2k4]

I found myself in a awkward situation last night at the stars $20 tourney... hour and a half into it, and I'm the chip leader. Normally a great thing right, except I've never been in this position before. I had 24k in chips and everyone at my table had about 3k in chips. How do I play with this type of advantage? Any advice? Any threads about the subject already on here?
