Motivation factors for pleasures!

Children see others doing some work and getting pleasures out of it. And they also note the delight and the satisfaction on their face appearing after that. By these the children are kindled to do those works by themselves and get pleasures that are hitherto unknown to them. Once they do and find out the pleasures themselves they go on to do the work repeatedly. They also express their happiness, delight and satisfaction on their face, and in words spoken. Other children watching these activities are also kindled; they too start to do by themselves. These are the basics of motivation for/and having pleasures from our environment!
