If you want to be happy, set yourself a goal that commands your thoughts, liberates your energy and inspires your hopes. Happiness is within you. It comes from doing some certain thing into which you can put all your thought and energy. If you want to be happy, get enthusiastic about something.
Dale CarnegieWe all have possibilities we don't know about. We can do things we don't even dream we can do. It's only when necessity faces us that we rise to the occasion and actually do the things that hitherto have seemed impossible.
