"To tolerate and maintain good wishes in the face of adversity requires tremendous inner strength. However, the rewards are immense"
This is like burning gold in extreme heat so that it glitters even more, all it's impurities having been washed away. No matter how much you subject gold to heat, it only gives more pleasure to those who behold it. Gold, however, can only derive the strength to do it from its innate qualities which enables it to bear all this heat and still make others happy. Real gold is tested thus, so is the character of a man who is sincere and strong. Adversities will come regardless, it's how we face them and what we do in their face is that matters. Rewards, needless to say, is that we become extremely precious, one in a million, the one who glitters more than other raw gold nuggets around, fetching more value for our what our worth is.
