What I especially like about this one is that if a mission is giving you a lot of grief, you have the option to skip it entirely. You get the bare minimum for passing, and you can continue on with the story, and you can always come back later and try again. (The option to skip doesn't show up until you've failed it 3-4 times, though...so you do have to at least TRY)

...No, I'm not very creative when it comes to this sort of thing.
