Rule of Threes - not particular business law, but life
This has nothing to do with business law and everything to do with life, which means that it actually does have to do with business law. This is a personal rule of mine (I had my rules even before Gibbs, for you NCIS fans)...
If something happens once ... it's an accident
If something happens twice ... it's a coincidence
If something happens three times ... I am doing something to contribute to it happening.
That's it. No exceptions. Even if "IT" appears to be totally "not my fault" if it keeps happening, I'm putting myself in its way. And it will keep happening until or unless I find out how I'm contributing and stop whatever that is.
Here's how it works when I tell the rule to people. "But my wallet was stolen three times, I had nothing to do with it" a friend cries. OK, so my wallet has never been stolen, what am I doing differently from you? Maybe my friend works in a really dangerous neighborhood. But that's still my friend doing something to contribute. He could change jobs. Let's say he loves his job. But right there he's gone from "not my fault" to realizing that this might be the cost of keeping a job he loves, and if it is, maybe he just shouldn't carry a wallet. Or he should just keep a very low limit credit card and a picture of his driver's license in his wallet.
Or maybe he keeps having his wallet stolen because he goes out drinking on Friday night, in cheap bars, and it's stolen there. He's contributing by his conduct. Change the conduct, change the outcome. Continue the conduct... well you know what they say, insanity is doing the same thing over and over and expecting a different result. Which, by the way, is a corollary to the Rule of Threes.
