I question that statement. We are surrounded by "luck". Will I still have my good paying job after this layoff?, will the new red car I just bought not be a lemon?, will my girl stay loyal to me after we're married?, will I live to be 100? It's there whether or not it is acknowledged, the rest of it is nothing but a big fat test called life. Since we are thinking creatures, the idea is to place as many factors in our favor as we can. Maintenance, in and of itself, is a hedge against luck, at least the bad kind. You may be more superstitious than you think.
