The fourth (of the four cardinal virtues) is supportiveness: this manifests as service to others without expectation of reward. (Paraphrased: Such service is not a mere conforming to some external rule of behavior, but instead a manifestation of your original nature).
If you realize that all things change, there is nothing you will try to hold on to. If you aren't afraid of dying, there is nothing you can't achieve. Trying to control the future is like trying to take the master carpenter's place. When you handle the master carpenter's tools, chances are that you'll cut your hand.
