If you want to guarantee a happy ending, you must figure out when to stop. Happy times do not last forever. Life ends in death, and death is usually grim. Generally, happy endings are only for the movies. Instead of seeking happiness, it might be prudent to look for contentedness. The one who is content with his station in life, has a happier train ride. The great railway journey of life begins in one place and ends in another. There is no jumping the rails or taking a side route.
