I've got to locate the book it's in, but a researcher determined that he could tell with a high degree of success which married couples would stay together and which ones would divorce. He based his determination on the ratio of pleasant to unpleasant experiences they had with each other. He said that for a couple to stay together there had to be five good experiences for every bad one.
From that information I created my Five To One Principle technique. It goes like this, for each unpleasant experience you have, purposefully create five good ones for yourself. This can be both enjoyable and time consuming, for some days, and in some environments. But, it works very nicely. If you use the Tools on this site, including the Add Pleasure tool, and lists of pleasures for each of the five senses, you'll have things ready to do whenever you have an unpleasant experience.
