Colossians 3:1-5
Since you have been raised to new life with Christ, set your sights on the realities of heaven, where Christ sits at God’s right hand in the place of honor and power. 2 Let heaven fill your thoughts. Do not think only about things down here on earth. 3 For you died when Christ died, and your real life is hidden with Christ in God. 4 And when Christ, who is your real life, is revealed to the whole world, you will share in all his glory. 5 So put to death the sinful, earthly things lurking within you.
Holy Bible, New Living Translation, (Wheaton, IL: Tyndale House Publishers, Inc.) 1996.

Allowing your mind to worry about your problems will lead you to sin.  Concentrating your thoughts on the things of this world is contrary to the new life Christ died to give you.  As new creation in Christ, you are to think on the things of heaven.  Keeping your mind focused on the things of God will keep you from focusing on the things of this world that you have no control over.  It is your thoughts that will determine your successes and your thoughts that will lead you to failure.  Whatever is in your mind will become your destiny.  If you think only on what is wrong in your life, you will never move beyond your fears.  But if you think on what the Word of God has given you, you will become what Christ intended you to be.  He died to give you life, you are to live to become Christ to the world.  Worry will rob you of time, energy, and success. Put to death the thoughts that lead to worry about your problems.  Instead think on the truth of the Word of God.  Banish the thoughts from your mind that lead you to despair.  Read what God has promised you and believe that it will happen.  Consider it done when you bring your need before God and do not take it back.  Jesus Christ is your real life and He died to give it to you.  Do not waste your time worrying. Let the Word of God fill your thoughts and pray about everything.  God will hear you and He will give you what you need to become the person He intended you to be.  It is by His power and by His truth that you will be free from wasting your time worrying.

Have a God Day!
