Thank God I have four sons. The mother/daughter relationship is one of mankind's great mysteries, and for womankind, it can be hellaciously complicated. My mother and I are quintessential examples of the rewards and frustrations, and the joys and infuriations it can yield.

It is very important to generate a good attitude, a good heart, as much as possible. From this, happiness in both the short term and the long term for both yourself and others will come.
