The biggest thing is adjusting thinking from "what is the absolute/relative strength of my hand" to thinking in terms of equities. There are a lot of spots in hold'em where you are essentially trying to put a player on a specific hand or a small range of hands, then deciding your best course. In Omaha it's similar, but you're looking at your equities and how they fare against different ranges. You'll find a lot of the time that you have a pretty high baseline equity. For example, the nut flush draw is super powerful and always has a good amount of equity, especially multiway.

The other thing you need to do is be prepared to win/lose/fling stacks around pretty wildly, much unlike hold'em where you aren't all-in very frequently.
