Fear of the unknown does not let one grow and prosper. Fear kills passion and faith. So kill your fears before they harm you. Courage is eternal, while fear is only temporary. Overcome your fears. Look fear straight in the eye and defeat it. There is nothing in this world that is impossible. Anything good that you want to achieve, is possible.
Our problem is that most of the time, we are passionate and enthusiastic about doing something, but there are forces around us, people around us that try to bring us down, and demotivate us. Try not to pay any attention to those negative forces. Do not let negative thoughts build in your head. Get rid of them the moment they are building up. Replace your fears with hopes. You will definitely feel the difference.
