It changes once you find or have something worth passing on. I don't have any kids or much materially, but I love to teach any of the skills or interests that I've picked up to any kid I get blessed with time with who shows even a mild interest.

Children, after about 3, are so much simpler to be around than adults. Though it can be draining at times if you have too many youngsters around, but your mind is chewing on an adult problem. What really gets the chemistry going is when you run into one where you see them running into the same problems you did growing up, or who has similar problems. The matching communication style but different origins make the entire experience somehow reinvigorating. Like a karmic balloon for your heart by helping someone avoid exactly retracing the life lessons you learned the hard way, and sometimes, they teach you a nugget of wisdom you'll kick yourself for not having caught..

Even if they aren't mine biologically, being a good (kind, wise, intelligent, enpathetic, independent responsible, creative, critical thinking, contributing person) is learned behavior, that the teaching is not straightforward for, but watching the lightbulb come on is one of the few things keeping me getting out of bed these days.
