A few years ago I heard a talk about success in college, and the speaker said a person needs a whole package of knowledge, attitudes, and skills to have a good chance there. The trio of terms has stayed with me: knowledge is not enough by itself, but we have to orient ourselves in positive ways toward the world, so attitudes as well, and we have to build up the skills that move knowledge and right attitudes productively into action in our lives. All three are essential: when thinking about change, or personal success, or group action and success--these are all easier to think clearly about if we look at all three aspects. Knowledge, attitudes, skills. Good talk, whoever you were.
