“ Don't you think it's better to be extremely happy for a short while, even if you lose it, than to be just okay for your whole life? ”

Don't think about making life better for other people who don't even deserve you, rather, focus on making your life the best, for yourself and those who love you.
Very little is needed to make a happy life; it is all within yourself in your way of thinking.
And will I tell you that these three lived happily ever after? I will not, for no one ever does. But there was happiness. And they did live.
