Motivate Our Child

How to motivate our children in order that they are wishing to do some thing for sake? Sometimes we just need to give them the wisdom words like this:

The work you do shows people the true you … so if you have to do something…whether it be cutting the grass, sweeping the streets or running a company do it to the best of your ability. For there will always be someone that will look at your work and say “Who did this?" You need to always feel that you can raise your hand with pride and say “I did!" (source)

Do you have others? Actually, it is not only for our children, isn't it? But we also need this words :)
