" Trust no-one, he thought bleakly. For an instant, he did not know if it was his thought or Lous-Therin's, but in the end he decided it did not matter. Everybody had their own goals, their own desires. Much the best to trust no-one completely except himself. Yet he wondered, with another man oozing through the back of his mind, how far he could trust himself. "

― Robert Jordan , The Fires of Heaven (The Wheel of Time, #5)
