“Labor, in itself, is neither elevating or otherwise. It is the laborer's privilege to ennoble his work by the aim with which he undertakes it, and by the enthusiasm and faithfulness he puts into it.”

Yes, excellent observation, I like it.!

A bit cumbersome, but intent is good....

Well said, not cumbersome at all, logically and grammatically correct. But I suppose "You get out of it what you put into it" could also suffice. ;-)

The honest hardworking man always gives it his best effort to improve the world's circumstances.  It is his duty.
