"Do not wear yourself out to get rich; have the wisdom to show restraint". In other words, "Don't weary yourself trying to get rich. Why waste your time?"
Ever seen that one? That comes from Proverbs 23:4. Pretty useful advice, I'll tell ya! Listen to what comes after that: "...for riches can disappear as though they had the wings of a bird!"
God chooses to bless us in different ways at different times, why not depend on him instead of wearing ourselves out?!? Wow.
