"The sooner I fall behind, the more time I have to catch up."
"Procrastinators: Leaders of Tomorrow"
Anonymous (but available on a t-shirt)
"Tomorrow is often the busiest day of the week."
"Procrastinate now, don't put it off."
"I'm going to stop putting things off, starting tomorrow!"
"If a thing's worth doing, its worth doing late."
"Work expands so as to fill the time available for its completion."
C. Northcote Parkinson (1958)
