I have three current favourites, although they may change through the years.
1: “In order to be irreplaceable, one must always be different.” - Gabriella Coco Chanel
2: “The woman who follows the crowd will usually go no further than the crowd. The woman who walks alone is likely to find herself in places no one has ever been before.” - Albert Einstein
3: “What’s great about this country is that America started the tradition where the richest consumers buy essentially the same things as the poorest. You can be watching TV and see Coca Cola, and you know that the President drinks Coca Cola, Liz Taylor drinks Coca Cola, and just think, you can drink Coca Cola, too. A coke is a coke and no amount of money can get you a better coke than the one the bum on the corner is drinking. All the cokes are the same and all the cokes are good. Liz Taylor knows it, the President knows it, the bum knows it, and you know it.” - Andy Warhol
and one final one from curb your enthusiasm; “pretty good. pretty pretty pretty pretttyy pretty good”.
