Interesting. I was forced to be responsible at a very young age by life circumstances. I was working full-time by 16 while still in high school and supporting myself by 18. For several years I worked 2 jobs. And at 25, I took on a house mortgage on a fixer-upper. Maybe that's why I'm glad to remember that in those times of hard work, and sometimes overwhelming responsibility, I still had fun.
And I can see why your own advice would be different.
