Second chances are rarely given and even more rarely taken. Why is it so hard to take the opportunity to choose another path? Is it because by doing so one admits the first choice was not the best nor the wisest nor the appropriate nor the right one? To step up and say, "that was stupid of me" indicates, acknowledges weakness when one wishes to be thought wise.
Why not choose another path, give one's self a chance to bloom and grow, find and develop new strengths, refine and perfect old skills? Because at just a pinch beyond middle age, going in a new and unknown direction can be overwhelming, terrifying. But if approached in the right frame of mind, a fresh start can be a wonderful adventure.
