Discouragement is an enemy of your perseverance. If you don’t fight against discouragement you will become pessimistic first, and lukewarm afterwards. Be an optimist.
To begin is easy; to persevere is sanctity. Let your perseverance not be a blind consequence of the first impulse, the work of inertia: let it be a reflective perseverance.
