Three important long term formative experiences when I was young:
1. Being a Boy Scout
I learned to respect the wilderness - to leave where I had ventured the way I found it and if I found any trash to pack it out.
2. Having a paper route
Learned the discipline to get up at 6 every morning rain or shine or big snow storm and below zero weather 6 days a week for 6 years for $6 a week using a Nike or a sled or by foot to deliver 75 papers. People were counting on me and I learned not to let them down.
3. Playing golf with my Dad
I learned the etiquette and honor system of golf - that you are only cheating yourself if you improve you lie or don,t count every stroke.
