Assurance in times of uncertainty

If you ask me what I want for my future, what I plan to do after college, what I want to do with my major, or even what I'm going to do next week--I don't know what to tell ya.. Sometimes I start flipping out inside my mind because I am so unsure of what I want to do with my life/career. But I believe in the Word of the Lord, and the Word says "A man's heart plans his way, but the Lord directs his steps." (Proverbs 16:9) All I am certain of is that the Lord is good and He will not forsake me. And as long as I live for Him and Him only, He will direct my steps.
