I have to find motivation to get things done early. The one thing that can get me motivated pretty quickly is when someone depends on me to get something done in a certain time period. For this reason I get things done at work effectively, but I struggle to focus on school often. In the future I expect this habit will dissolve and the skill to become natural, but for now it takes a ton of self-manipulation and jumping through logical hoops to finally get myself to work on some things.
And, yes, I do work quite a bit under pressure.
Oh, and here's a quote that's been able to get me off of my ass a few times:
“If you don't have time to do it right, when will you have time to do it over?”
