This is what I have observed to be good: that it is appropriate for a person to eat, to drink and to find satisfaction in their toilsome labor under the sun during the few days of life God has given them—for this is their lot. ~Ecclesiastes 5:18
Men become wise in spirit when we stop focusing on what we do for a living and start focusing on why we do... anything.
Worry less about whether you have the right or wrong career path. Instead, keep your eyes on serving God no matter what you do. This is how you find that elusive contentment and happiness.
God's desire is for you to love Him first, take care of your heart, and to love and serve others. Let your job be the instrument through which others meet God.
GO DEEPER: Psalms 90: 14-17
