In success of life these two things are most important as I found in my personal experiance. And if you add one more thing, that is dermination then no one can defeat you. Long ago when I was dispared coz of my failure at one of stage in my achievements, I decided to break my journey. Alone in my office thinking what to do. Suddenly I saw an ant trying to pull out a piece bread which was almost double of its size. It was climbing a wall which paved by glossy tiles, climbing, falling, climbing, again falling... After striving hard it reached to its place. But it didn't rest even a moment and turned back to get another piece of bread.
