My heart, display toward all your friends a changeful character, <br /> Adding into it the disposition that each one has. <br />Adopt the disposition of the octopus, crafty in its convolutions, which takes on <br /> The appearance of whatever rock it has dealings with. <br />At one moment follow along this way, but at the next change the color of your skin: <br /> You can be sure that cleverness proves better than inflexibility.<br /><br />Theognis<br /><br />http://www.poemhunter.com/poem/fragments-lines-0213-0218/
