All that is required is that he must recognize new challenge when it presents itself, and accept it zestfully. If he has been doing this all of his life, it will be easier for him in the later years, but in one form or another the opportunity awaits everyone, if he will only seek it. For most men there should come a time of shifting harness, of lightening the load one way and adjusting it for greater effectiveness in another. That is the time for the second career, time for the old dog to perform new tricks. On the other hand, it may bring in much needed support.
All life is an experiment.
The more experiments you make, the better. Ralph Waldo Emerson Prepare to live by all means, but for Heaven s sake do not forget to live. One cannot control the length of his life, but he can have something to say about its width and depth. Life was meant to be lived, and curiosity must be kept alive. One must never, for whatever reason, turn his back on life.
