just before my dad died he said 'you only live once, enjoy yourself while you're here' and 'you can't take it [money] with you' and 'be happy with what you have got, don't complain about what you haven't got'
I live life on the positive side, yes, I could have more money, but I could be a lot worse off. take a step back and look at your life, have you got a roof over your head? eat food every day? happy relationship? stop worrying about what you haven't got, enjoy what you have
