Why should we stop worrying about our future and start to concentrate on developing ourselve?

An important thing is that you concentrate on developing yourself. Whatever others may say or do, those who have established their own solid sense of identity will triumph in the end. The great Japanese author Eiji Yoshikawa (1892-1962) wrote in his novel Miyamoto Musashi [an account of the seventeenth-century master swordsman of the same name]: "Rather than worrying about your future, thinking 'Perhaps I should become this or perhaps I should become that,' first be still and build a self that is as solid and unmoving as Mount Fuji."
