Encountered this intriguing quote via Frank Chimero regarding the drive that humans have beyond the biological and reward response. Very interesting:

We do things even when they don’t satisfy our biological urges, win us a reward or help us avoid a punishment. We play musical instruments during the weekend simply to master something challenging. We quit high-paying jobs to take new jobs that are less lucrative but more meaningful. Human beings, says University of Rochester psychologist Edward Deci, have an “inherent tendency to seek out novelty and challenges, to extend and exercise their capacities, to explore and to learn”. Few would deny that this third drive is also part of what it is to be human.

There are those with more insightful commentary on this than I could provide but I like the idea of a Challenge Drive. Choosing to do something not because it is easy but because it is hard is something we should all get behind.
