Last Minute
There has to be some part of me (all of me?) that loves leaving just enough time for everything. An entire day with a 5pm deadline is simply not as juicy as only having 44 minutes (23 minutes...6 minutes...30 seconds!) to get it done.
I once heard that the key to productivity is something like having a good idea and not quite enough time to do it. I definitely have the second part down.
