Soren Kierkegaard has a tidy little piece, “Dare to Decide” in which he extolls the virtue of action and declaims cowardice. Funnily enough, the reason to act? Because God demands it. Eternity persuades it. Cowardice rewards nothing but pride. Cowardice is a version of pride because one trusts in his own strength rather than in God. The piece is a high brow of version “Just do it.” Really in the end if you at a crossroads, holed with fear, there is nothing to do but to dare to decide. Here’s the ending paragraph.
“Therefore, dare to renew your decision. It will lift you up again to have trust in God. For God is a spirit of power and love and self-control, and it is before God and for him that every de cision is to be made. Dare to act on the good that lies buried within your heart. Confess your decision and do not go ashamed with downcast eyes as if you were treading on forbidden ground. If you are ashamed of your own imperfections, then cast your eyes down before God, not man. Better yet, in weakness decide and go forth!”
You might not believe in God; I am not religious either but I still think those are some powerful words.
