God commanded courage three times to Joshua — because courage is a choice before it is a feeling. The ground of that courage is not Joshua's ability but God's presence: “with thee whithersoever thou goest.” There is no place you will go today where He is not already. Courage is simply acting on that truth before your feelings catch up.
Be Strong and Courageous
Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest.
Lord, I choose courage today, not because I feel strong, but because You are with me wherever I go. Amen.
