Patience, perseverance and persistence.

Patience is the ability to stay calm and endure something very annoying, perseverance is the ability to continue to achieve something or a goal despite difficulties, persistence is the ability to continue to do something to achieve a goal despite people's opinion of being foolish or annoying.
These three qualities are whats very necessary to succeed against all odds, a friend of mine on facebook said, " I wonder if I was Abraham Lincon, would I have continued trying after much effort and less result". Many would have stopped trying after the third attempt.
Nothing in life is consistent, some people would achieve their set goals on first trial, while some would have to try and keep trying, but what distinguishes successful people from those that aren' t is the ability to conceive a dream or goal or something they wish and try their possible best to achieve the goal or dream.
These three qualities patience, perseverance and persitence are very neccessary to live a life of achievements, cause with them failure wont be a setback, it would be a reason to replan and make a much more fool proof plan.
