My First Tournament

[Alaskan]

Hey guys, I've been playing cash games mainly for about a year now but now that I have a steady bankroll I've been thinking of trying my hand at some tournaments. The thing is I need some pointers before I start. I know my patience-is-golden cash game style will not work with rising blind structures and more aggressive play. So what do you guys suggest is a good strategy? How should I play differently? What are some really simple tournament nuances that I should learn right now instead of in my first hour at the table?

Any help would be greatly appreciated.
