A samurai who does not polish his sword every day will find that when most he needs it, the sword has grown rusty.
Everyone has a skill that they are good at, a skill others would describe as a natural talent to this person. This quote reminds me that no matter how skillful you are, if you don’t practice, you will lose it. Another great reminder of why you shouldn’t take anything you consider your talent, for granted — but instead, practice and invest to get better at it. With true passion, you may one day become the best in the world at it.
