Perseverance is persistence in doing something despite difficulty. Constancy is the quality of being faithful and dependable.

Anthony Mangun said, “A good leader begins with an unwavering belief in what he is doing and refuses to quit, pressing on in spite of setbacks and roadblocks. Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish. In a race, it doesn’t matter who starts, but who finishes. Those who persist, prevail.
