Found this while reading a business managment book
Its a statement of the finding of a Polish psychologist on what makes people feel good
"The types of activity which people all over the world consistently report as most rewarding - that is, which make them feel best - involve a clear objective, a need for concentration so intense that no attention is left over, a lack of interruptions and distractions, clear and immediate feedback on progress towards the objective, and a sense of challenge - the sense that ones skills are adequate, but only adequate, to cope with the task in hand."
Pretty much coves it all for me
