Musings

Hard work and sacrifice in the absence of self-deception (if someone falls prey to self-deception, they could work hard at something to distract themselves from what they truly know they need to do) is bargaining with the future—asking for a better set of circumstances through your immediate offerings.  

I’d argue that putting in effort while knowing the outcome is uncertain could be roughly defined as courage.  And enjoying the effort without expectation of reward could be roughly defined as harmony; I’d argue you’re voluntarily enjoying the strife of living without becoming embittered or entitled.
