Waters Law

Somewhere between Murphys law and A watched pot never boils. Waters Law: Nothing you want to happen will happen until its inconvenient or impossible for you.

Example of Waters Law:
You have been asking for a raise for months, you deserve it. In frustration you sign on to a different company for a raise. The day you do your boss calls you and tells you you're getting a raise worth more than your salary at the other job.
