Remember, happiness doesn't depend upon who you are or what you have; it depends solely upon what you think. So start each day by thinking of all the things you have to be thankful for. Your future will depend very largely on the thoughts you think today. So think thoughts of hope and confidence and love and success.
Dale CarnegieBy all means take thought for the tomorrow, yes, careful thought and planning and preparation. But have no anxiety.
Dale CarnegieIf 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 CarnegieMix judgement with ambition and season it with energy. It makes a splendid recipe for success.
