Becoming fearless isn't the point. That's impossible. It's learning how to control your fear, and how to be free from it. Fearless is having fears. Fearless is having doubts. Lots of them. Fearless is living in spite of those things that scare you to death. Don't be pushed around by the fears in your mind. Be led by the dreams in your heart. Courage is feeling fear, not getting rid of fear, and taking action in the face of fear.
You were put on this earth to achieve your greatest self, to live out your purpose, and to do it courageously. Successful people have no fear of failure. But unsuccessful people do. Successful people have the resilience to face up to failure, learn the life lessons and adapt from it. Fear robs you of your freedom to make the right choice in life that can bridge the gap between where you are and where you want to be. On the other side of fear, lies freedom. If you want to grow, you need to be brave and take risks. If you're not uncomfortable, you're not growing.
