The convictions that leaders have formed before reaching high office are the intellectual capital they will consume as long as they continue in office. There is little time for leaders to reflect. They are locked in an endless battle in which the urgent constantly gains on the important. The public life of every political figure is a continual struggle to rescue an element of choice from the pressure of circumstance.

Henry Kissinger (1923-2024) German-American diplomat
