Remember these sayings "What doesn't kill you makes you stronger," "Women are like tea bags, you never know how strong they are until you put them in hot water" and "the world breaks everyone and afterward many are strong in the broken places."
I choose to think that all the little set backs that we face are preparing us for the difficulties we will ultimately confront in old age. Get tough now to prepare. Getting old is not for sissies as they say.
