James B. Stockdale said this quote

“ A properly educated leader, especially when harassed and under pressure, will know from his study of history and the classics that circumstances very much like those he is encountering have occurred from time to time on this earth since the beginning of history. He will avoid the self-indulgent error of seeing himself in a predicament so unprecedented, so unique, as to justify his making an exception to law, custom or morality in favor of himself. The making of such exceptions has been the theme of public life throughout much of our lifetimes. For twenty years, we've been surrounded by gamesmen unable to cope with the wisdom of the ages. They make exceptions to law and custom in favor of themselves because they choose to view ordinary dilemmas as unprecedented crises. ”
