I have always been optimistic and thinking that happiness was always going to be with me, as long as I made each day happy. To wait for other people, or fate, or whatever to bring me happiness was awaste of the time I waited.
Make your own happiness and you will be happy ever after.
I know that is glib and easy to say,(or write), but I do believe it to be true, it is not always easy to do when you are in s***y circumstances though.
good luck XX
