Fear isn't necessarily a bad thing which is a misconception a lot of people have. It warns you of something that is potentially dangerous or threatening to your well being. It sharpens your awareness and makes you more alert. The problem arises when humans succumb to fear. When that happens, they can become immobilized and that is when they are truly helpless. It is OK to have fear but try not to let it overwhelm you. Stick to the mindset of "fight or flight".
I must not fear. Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain.
