Happiness is not a matter of intensity but of balance, order, rhythm and harmony. Thomas Merton
The best lack all conviction, while the worst are full of passionate intensity. William Butler Yeats
The basic problem with my love relationships with women is that my standards are so high - and they apply equally to both of us. I seek full-blast mutual intensity, fully fledged mutual acceptance, full-blown mutual flourishing, and fully felt peace and joy with each other. This requires a level of physical attraction, personal adoration, and moral admiration that is hard to find. Cornel West
When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favour of the belief which he finds in himself. Bertrand Russell
If a leader doesn't convey passion and intensity then there will be no passion and intensity within the organization and they'll start to fall down and get depressed. Colin Powell
