For what has man for all his labor, and for the striving of his heart with which he has toiled under the sun? For all his days are sorrowful, and his work burdensome; even in the night his heart takes no rest. This also is vanity.Ecc 2:22 — Ecc 2:24
Nothing is better for a man than that he should eat and drink, and that his soul should enjoy good in his labor. This also, I saw, was from the hand of God.
This must be why having a passionate purpose in work is so important. Success is not a destination or lots of stuff, but making the most of the journey. Perspective!
