One of the key reasons of doing anything in life is the sense of achievement that it brings, from education to work and pretty much anything else you do. Sure, money, fulfillment and career count, but the fact remains that if you feel you’ve accomplished something, you’re more likely to be happy than with anything else. Studies have shown that even in workplace, those employees are usually happier who get recognition of their work in addition to compensation, as opposed to those who continue to perform their duties without their superiors acknowledging their efforts. As Homosapiens, we are programmed genetically to pursue this sense of achievement, and this fact adheres to basic human psychology.
