This has become a bit of a mantra for me. I really do think it's vitally important to be able to make a distinction between poise and posture. Although the dictionary definition of posture is acceptable to me, the way people actually relate to the word, how they filter it when they hear it, is generally unhelpful. The moment someone makes an effort to physically improve their posture they do so in an unsustainable way. By understanding poise the physical effort is reduced and sustainability is increased.
