A ship ought not to be held by one anchor, nor life by a single hope.
~ Epictetus

Consult not your fears but your hopes and dreams. Think not about your frustrations, but about your unfulfilled potential. Concern yourself not with what you tried and failed in, but with what is still possible for you to do.
~Oliver Wendell Holmes

Hope, like the gleaming taper's light, Adorns and cheers our way; And still, as darker grows the night, Emits a brighter ray.
~ Oliver Goldsmith
