● If you are afraid of the ups and downs of the rocks ahead, life will always be a stagnant pool.
● Cowardly people will only hold back, reckless people can only be burned, and only truly brave people can be invincible.
● Our world will never give a medal to a sad laggard.
● The steps of a ladder are never used to put feet, but only to let people put their feet for a while so that the other foot can climb up again.
● If you don't run for a kilometer at ordinary times, it will be difficult to sprint for 1 meters in time.
