1. To make it your mission to complete your work right before it is due.

When you are overwhelmed and procrastinate so that you only have an hour to do your project before it is due.
When you're lazy and have to mission so that you don't fail.

2. To cram study before an exam because you were too lazy to study beforehand
I have a science project due in 2 hours... crap! Missioning time!

Shoot I forgot to study! Missioning will be the only way I pass this darn test! :O
