Since we control neither life nor death, we should make the best of things as they are, and give ourselves fully to the time left for living. Being what the times call for and doing what is needed is a good way to live our life. What would we gain by not doing that? What would we lose by doing that? Live to see what is happening, to know what's what and what is called for in response in each situation as it arises. Do it, and then live to see what happens in response to that, and what is called for there, and do that... And so on throughout the time left for living. If you have a better idea, live in its service all the days of your life, and may they be days well spent upon the earth!
