Pessimism or optimism, it does not matter. The matter is how you can improve yourself base on your characteristics and personality.
People often think that optimism is better than pessimism. Because the optimistic is always happy. They have a lot of beautiful hope about their future. They’re very confident. They know everything will be ok soon. Whereas, the pessimistic seems to be nagative, less confident, doubting or depressed.
Actually, both kinds are equal in opportunity and challenge.
It is said that nothing is impossible. But in real life, there’re a lot of things is impossible. The ability of a person is limited. The optimistic can easily think they can do something beyond their ability but it’s just a illusion. The unexpected failure can makes them never trust themselves any more. It’s hopeless. But the pessimistic is more careful before making any decisions. They define themselves exactly and as a result, the rate of their success is obviously higher.
