Does exist any theory stating something similar to this?:
We are born with basic biological urges (urge to eat, to urinate etc.) and a pleasure feeling from eliminating these urges, for example eating. As we grow up we start to associate certain behaviors with higher chance of getting more of these pleasures from eliminating basic biological urges. To these associated behaviors our brain is able to assign pleasure feelings. For example, we get happy after receiving money because we have associated money with their ability to ensure more pleasure feelings from eliminating these urges to the future.
PS: Sorry for my English. If you don't understand anything, I can try to clarify it.
