God has given us a great mind. And of course we should make our lives as good as possible, we should be diligent, we should work hard, we should show commitment. But all based on the realization that we are putting our lives under the guidance of the almighty Almighty.

Psalm 37:5-6 (NIV)

“Commit your way to the Lord; trust in him and he will do this: He will make your righteous reward shine like the dawn, your vindication like the noonday sun.” (Psalm 37:5-6; NIV)

Why can we put our lives under the guidance of God?

Because God has glorious plans of salvation and blessing for us (Jeremiah 29:11-14). God wants the best for us, in all areas of our lives.
So why should not we benefit from the tremendous wisdom and tremendous power of God?
 
God’s wisdom is indescribably greater than our knowledge. “Trust in the Lord with all your heart; do not depend on your own understanding. Seek his will in all you do, and he will show you which path to take.” (Proverbs 3:5-6; NLT)
 
Tell your God: Always let me know what Your will is, my dear God (or, of course, in your own words). Talk to God. Read the Bible daily if possible. You will realize your relationship with God is getting better and better. And always strengthen His help in your life. You are on a magnificent path. • Think your best days are behind you? Not according to the Bible
