Don’t invent rules. A huge proportion of those “oughts” and “shoulds” that you carry around are most likely needless. All that they do for you is make you feel nervous or guilty. What’s the point? When you use these imaginary rules on yourself, you clog your mind with petty restrictions and childish orders. And when you try to impose them on others, you make yourself into a bully, a boring nag, or a self-righteous bigot.Now, I do have life rules, but they are lessons learned rules, so I think they're okay.
"Always wear comfortable shoes."
"Never live with your best friend."
[Corollary to Rule #2: "Live with someone who can be your best friend."]
There really are only 2 rules, but I'll jokingly add them as they come up. Like, Rule #23 (in the Travel subset of rules) "Always use the bathroom when you get a chance."
Any to add?
