Anyone can manipulate words and stretch the facts to suit their short term objective. However, it is difficult long-term to fake behavior and eventually your words will catch up with you.
Leaders cannot be low energy people – it is that simple. When you walk into a room the energy level should automatically pick-up. When you meet someone who is low energy your own positive energy should be infectious. Success at anything requires thoughtful action. You need to focus like a laser beam and plough forward despite the inevitable obstacles and distractions. When other people are saying “no” or this is too hard, you have to be able to say “yes” and encourage them on anyway. As with everything you need to lead by example.
