Never be afraid to offer a smile; sure the risk is that a few foolish people may misinterpret your kindness as weakness, but the sweet reward is that as you make new friends and encourage others, the foolish will learn the error of their ways because you did at least show them your teeth.
Your love life is insignificant when it comes to raising your children to be respectable human beings. The moment you see them suffer or lower their standards because of your selfishness, is the day you should realize that nothing matters more than them. You are not just the queen or king of your fairy tale. The real story of your life is the gift of time God gave you with them.
