After a while, you get to see things from a decidedly different point of view, one that could be considered jaded – sadly – but also one that is experienced over many circumstances. I do not consider myself particularly wise, just experienced at best. I wouldn’t presume to classify myself as wise at all, given some of the bonehead mistakes over the years.
I do know that worrying doesn’t do anything for anyone except make things worse for you and everyone around you. I don’t have any magic cure for this particular rule, or suggestions (not wise, remember) or directions… just the idea that there are some things and some times where you will come to the realizations that you can get rid of a great deal of problems by not worrying about what you cannot control (see Rule #1 for reference).
