In the face of adversity and uncertainty, you have to be brave. Being brave gives you an advantage. 
It allows you to think and use a rational decision-making process.

If you are enveloped by fear you will be drowned by your emotions. This deprives you of being objective in discerning our current realities.

Emotions block you from harnessing the power of your rational mind. Soldiers who wanted to live are afraid of dying but because they are brave they are able to use their mind to create strategies that help them avoid danger and increase their chances of victory.

To emphasize the power of being brave, William Faulkner said,  “You cannot swim for new horizons until you have the courage to lose sight of the shore.” 

Be brave. Rejoice the there is adversity, an opportunity for growth and progress.
