Bon: not sure. Difficulty is the vinegar of life.
For me, I like vinegar. It is an essential element in ketchup and most salad dressings. It is in most barbeque sauces and of course all pickles.
How dull would life be if everything were sweet? We all need that kick in the ass from time to time.
If we figure out how to deliver that kick in the ass in conditions of peace and prosperity, then we have most of the problems of life solved.
