Today I had a paper due. And I had to get it done today, since my professor had kindly extended my deadline for a week. So today when I woke up I gave myself a deadline. I had to get a rough draft done before I left for a coffee get-together. And the deadline worked! It's hard to even give myself a deadline at home because I can always find time to cram working on a paper. However, since there was a fast approaching deadline, finishing was easier than it usually is.
Also, working when it's cold outside and you have some black tea to wake you up is extremely motivating too. And yes, for me, a little bit of black tea does the trick. I have very low tolerance for caffeine!
