visualize
-Think of a time in your life when you were confident and what it felt like. Try to recreate that feeling and remember how good it felt. If you can't think of a specific instance, just imagine yourself in a situation where you are confident and then let the feeling flow through your body.
-Visualize yourself being successful at whatever endeavor you have in front of you. This may sound cheesy but studies have shown that people who visualize themselves succeeding before they try something tend to perform better at it than those who don't. -Focus on the situation at hand. Don't think about what might happen or what could go wrong. Just focus on what is happening right now and how you can make it better.
