As soon as you think you have succeeded enough, you have a downfall. And when you have fallen down down, and have accepted that failure; your path for rising has begun. Rise and Falls, Success and Failure, Negative and Positive are two sides of a coin, you cannot have only one. You get the other, in the deal!
Life always keeps moving to and fro, there is no stopping.
Learn to be centered with yourself, learn to be always zero, neither positive nor negative. Learn to be free from the maya of Good and Bad.
