If it wasn't for procrastination...
If it wasn't for procrastination, a lot of things would never get done.
Think about it. How many things, useful things, have you worked on and finished, because it was a good way to justify putting off that BIG thing that you didn't want to do?
Another problem is the occasional positive reinforcement you get when you put off (e.g.) writing that report, only to find out that the project has changed direction and the report isn't needed after all. Look at all the time you saved by procrastinating!
