I am reading Flow at the current moment. I came across this wonderful concept regarding difference between pleasure and enjoyment.
I used to think they are the same but the author made an imporant distinction. Pleasure can be felt with out enjoyment with help of chemicals but enjoyment can only be experienced with investment of attention.
Enjoyment leads to learning. Another wonderful example he pointed out is the learning and enjoyment experienced by children, how growth and enjoyment are correlated.
Same person grows up to be an adult who seek extrinsic reward for everything they learn and there stops his learning, hence enjoyment and pleasure before his only positive experience.
Several succesful people have expressed the same notion in their interviews and biographies. For example Steve jobs learnt caligraphy with no expectation of extrinsic reward, he did not know any way caligraphy would benefit him not did he even get college credit for doing it. He just enjoyed learning caligrpahy. But later on in this skill formed the basis of type setting in PCs..
Another exmaple from my life is, I was blogging about ODI and wanted to start a professional blog, because I enjoyed the experience of blogging not as much as I would like to but writing creates a sense of flow and it makes me happy. My friend asked why do you do it, do you get any monitory benefit. I never thought about why until he asked I could never put a finger on it but when I read abotu flow.. I could make it out.
