So sidewalker_Principle noted that we all seem to be an older, fairly successful gang here. What's the one best life lesson you've learned?

> Mine: I don't have to, nor want to, put up with other people's shit. Your problems aren't mine. Your emergency is not even remotely my problem. That's what OP said. A lot of people believe that, so... My life life lesson is to not whine, complain, bitch or moan or air my complaints to anybody except the few people who care and reciprocate. Even then, keep it to a minimum. Tell it to your dog.
