"Don't waste a minute not being happy. If one window closes, run to the next window- or break down a door."
Happiness is not a onetime stop, being happy is an attitude that must stay with you in every place that you go in life. Those who are truly happy are happy when they are afraid, because they know that ultimately everything is going to be all right. Those who are truly happy are happy when they fail because they know once they get back up and try again they have a better chance of overcoming whatever obstacle may be in their way. Those who are happy are peaceful in times of stress because they know that keeping a positive upbeat attitude is one of the only ways to make the feelings of stress in their lives subside.
Those who are happy understand that happiness is a commitment, not an achievement. Live your life happily, to the best of your ability, and make sure that you never travel without this uplifting attitude from station to station.
