Before you start walking on the path of your dreams, or when you start walking, fear will come in the way. Fear of the unknown, fear of not being in a comfortable zone, fear of losing it all, fear of criticism, fear of failure, fear of success, fear of change, etc. It's just part of the process, its part of life and its part of your path. Know and believe that whatever fear you have you can conquer it with the help of God. Ask him to help you, because believe it or not God wants you to follow your heart. He is the one that planted those seeds of dreams in your heart. All what you have to do is get closer to God, feel His love, feel the strength that He is giving you to conquer your fears and to walk on that narrow path that He has designed for you. All what you have to do is believe, have faith and never lose focus on your purpose and your dreams and you will be able to kill all of your fears.
