Fasting helps us develop a strong personality and character. Not giving in to the temptation of having a sip of cold water even when no one is around really says volumes about a person's self control. It instills other great qualities in us such as patience, will power and determination, which we need in our lives and fasting helps us in getting the hang of them. And don't forget fasting instills humility in us by giving us a feeling of deprivation which normally the affluent ones never face. We learn that life isn't always perfect, not for,any of us anyway, and that leads us to developing another gigantic characteristic: generosity. We learn to give because we learn exactly how it feels to have nothing.
