I go "above and beyond" all the time, but not because I think it's going to get me "somewhere". It's the type of person I strive to be, and that's good enough for me.
As much as I sometimes wish I could be rewarded just a bit better for going above and beyond, I have to agree with you here. I appreciate your philosophy.
Ultimately, intrinsic motivation won’t always make us rich, but it might help us be happy and fulfilled. And in the rare occasion that health, wealth and happiness all align, what a good life we can enjoy.
