You know the feeling, the butterflies in your stomach and the fluttering in your chest.  You feel it when you’re presenting in front of the class or sharing your good idea with your boss.  It feels like your heart is going to beat out of your chest and all the “what ifs?” swirl around in your mind.  What if I mess up or fail?  What if my boss thinks my idea is stupid? What if the people in my class laugh at me?  You might wonder, is this anxiety?  Or is this just a normal worry?
