"Even though the fig trees have no blossoms, and there are no grapes on the vines; even though the olive crop fails, and the fields lie empty and barren; even though the flocks die in the fields, and the cattle barns are empty, yet I will rejoice in the Lord! I will be joyful in the God of my salvation!" (Habakkuk 3:17-18)
True joy, peace of mind, happiness and fulfillment in life is a function of your relationship with God and not in the abundance of things which you possess or your "accomplishments and successes in life"! This is the ONLY reason why you will still find strength to rejoice in the Lord God your salvation.
Wishing you and yours a fulfilled and peace-full weekend!
