If you lived to be 100 years old you would have only lived 36,500 days. Isn't that incredibly weird? 36,500 days doesn't seem like a lot of time and that is because it isn't. Naively from our childhoods, we think that we have all the time in the world. As we get older and, presumably more wiser, we realize that as Sensei used to say, "There is no time left." If "there is no time left" then that would compel us to use our time and lives wisely. Whatever we have been putting off must get done. Whatever we have wanted to say, needs to be said. Life is too short to leave things unsaid, undone or to have to tolerate things.
Gandhi said, "Live as if you were to die tomorrow. Learn as if you were to live forever." From there we can say, "Live you life as if you would die tomorrow and train as if you would live forever." Please train hard because there might not be a tomorrow.
