" try to remember that it's always your emotion -backed demands that are really the practical cause of your own unhappiness" The art of happiness means learning to be with and work with the cast of characters you have brought into your own life. Retreating won't do it. Coming on like a ten tun truck won't do it either. Emotionally accepting and patiently working will get you the most that is gettable" From a prescription on happiness.
Life goes by rapidly
Don't delay
Don't put it off
Don't wait untill you have some spare time
Don't wait untill the time is right.
