Giving up on a difficult chase when you are never getting to the destination is a common trace in most human beings. Anytime I am asked to differentiate between a successful person and a failure, my answer has always been simple; a successful man is the one who believes in perseverance while a failure dwells on giving up.
The above distinction points out the correlation between Perseverance and Success. Without perseverance, Success becomes a conception which is fully attributed to Luck.
