1 - the more time you spend with your kids, the more
they learn from
you. Be their softball coach (or soccer, basketball, etc.) If you can't
be the coach, be the team parent. Cheer them on, don't criticize them.
At the end of the day, you'll be surprised how much they've learned
from your behavior.
2 - kids are going to rebel at some stage, probably
early teens. You
did, too. Accept it, be ready to deal with it. The best way to do that
is to be ready to explain why you think and act the way you do. As
Brian said, they really do learn more from what you do than from what
you say.
3 - keep the rebellion within bounds. No drugs, drunk
driving, or
unprotected sex. No criminal acts - theft, beating up others, etc. (And
it doesn't hurt for you to live that way, too.)
4 - if they make their bed, they lie in. Don't always go
rushing in
to clean up their messes. If they break something, they bought it.
