Work
We know that with regards to work everything can be done at the last moment. If you have to do some research before the qualifier exam, all you have to do is spend a sleepless month. Sometimes I wonder why do we work in this fashion. Its always possible to avoid those sleepless nights. Though I think those sleepless nights provide you the kick you need for working. So all you have to do is, enjoy for a long time, choose a deadline and then work your ass off to meet the deadline. You will get high on work and be happy about it :)
