McCullough's law

Pain comes quicker than you think and pleasure comes slower.

This is just a hypothesis. Send in your counterexamples.

A couple of pro examples:

1. When you're sitting at the bar nursing a beer and minding your own business, people who take offense punch you in the nose much quicker than you would expect them to.

2. When you are riding the elevator, you are more likely to beginning stepping out before your intended stop when you are going on break, than when you are going back to work.
