When I was a pre-teen, my mother once told me "I never want to hear about you...". I expected to hear a sweeping restriction and my brain was already primed to file the next tidbit with other adult "advice" - material that had no supporting context in my experience (largely because my experiences were so few, though I didn't know that then).<p>Instead she finished with "...committing any crime you can't retire on". It was a game-changer for me. This advice...had context. It wasn't a absolute "no", nor did it rely solely on experiences I didn't have. It extended on experiences I _did_ have into a broader area.<p>Throughout most of my teenage years I avoided all the worst situations that peer pressure was steering me towards, not because I suddenly properly calculated the risks - I could no more visualize the impact on my life that any kind of conviction would have than I could before - but because I was better weighing the _gains_. Instead of "doing this will prevent me from losing ranking in my social hierarchy" it was "doing this will not gain me material improvement". Instead of "if I fail I will get in trouble" it was "I will be disappointing because I tried, regardless of success".<p>Eventually, of course, I built my own ethics structure about why crime/rudeness/unnecessary risk-taking were undesirable, but this one statement gave me time to do so that I might not have had.<p>I highly recommend it to all parents.
