In this world, there are two simplest ways to change yourself, the most effective and the lowest cost. 1 is fitness, which can effectively change ourselves from spirit to temperament to figure, turn us from a fat man into a delicate thin man, and also turn us from a frail person into a healthy person.

The second method is reading. Reading may not really change our destiny, but it does sublimate our temperament. We should read as many good books and philosophy books as possible. In these books, we can absorb nutrition and knowledge through reading, broaden our horizons, rebuild our world outlook, values, outlook on life and even reshape our lives.

So if we really don't like ourselves now and want to change ourselves, then we will start running tomorrow, pick up a good book and let ourselves know more. Slowly, with the passage of time, we will certainly create another self, a more perfect self.
