“To bring up a child in the way he should go—Travel that way yourself.” - Josh Billings

Isn't that so true.

Few examples to support this :

1. If you do not want your kids to swear, do not swear in front of them. How else you can explain to them that it is bad?
2. If you want to them to watch less TV, decreased your TV time. Otherwise, how would you explain it to them?
3. If you want to cultivate the habit of exercise in your kids - start doing it yourself.
4. If you do not want your kids to shout, stop shouting yourself.
5. If you do not want them to walk barefoot (or other way round), do it yourself.

Most of the kids have excellent observation power. In fact they learn by observing. First few years are very important. Sometimes you would say that - what does she know, she is a kid. She may not understand, but she has observed it and stored in her mind. Later she may connect this image with something else she sees. That may be good or bad. you can not control.
