Example Input: Article: "He who can have patience can have what he wants," said Benjamin Franklin. They say patience is a virtue seldom found in women and never in men. This may or may not be true, but it's fair to say that there is nobody on the earth who couldn't benefit from more patience. Patience is necessary for success. It is said that "all good things come to those who wait". Many of the great scientists have remarked that their scientific discoveries came only through patient perseverance . Edison said, "Genius was 99% perspiration and only 1% inspiration." Patience teaches us to value the effort and not just the success. It is a mistake to think that happiness can only be obtained through achievements. Patience brings peace of mind. When we desire certain outcomes , we'll have no peace of mind. Even if one desire is filled, the nature of desire is that more will appear in its place. There is no end to human desires. Patience means we will work with an attitude of detachment . Patience can transform suffering into joy. Throughout life we suffer injustice; the best healer is patience. Through being patient and accepting our situation, it's quite possible for our suffering to be transformed. Sri Chinmoy said, "If failure has the strength to turn your life into bitterness itself, then patience has the strength to turn your life into the sweetest joy."
