answer:One thing I have learned over the years is to seize every opportunity I can. Sometimes one cannot because of conflicts with other opportunities, but for the most part after 56 years I have only regretted things (jobs, friends, women, fun, work) I did not pursue. Fresh things help a worn out stressed tired person stay fresh. It only takes one good nights sleep and a healthy diet to have the energy. Be open to new things! Date that girl! Try that food! Go on that trip! Switch careers!
