There is a harmony in being fearless. It means that you recognize the challenges and the potential for failure, and you push on. We live in a world where fearlessness has been replaced by "what will they think". Therefore, many grand ideas that would change our lives are tucked up in someone's mind because they are afraid to bring this idea forward.
It is our FREE WILL to be able to move forward and do what we need to do for ourselves. We need to be able to live with only ourselves if we should not achieve. The others do not matter.
