Book excerpt: Confidence is a choice. Scientifically, we can learn how. We've been misled, often lied to. Confidence isn't inherited or vicariously inspired. You don't just get it by working hard or faking it 'til you make it. It's not a result. It's a requirement. Sadly, it takes most people 60+ years to figure it all out and reach their confident best. Now anyone can learn to give and get real confidence. Endorsed by top academic, business, and non-profit leaders, Confidence is a Choice will fundamentally change the way you act, react, and interact. CLARIFY what confidence is (& is not), how it works in our brains & impacts behavior. CALIBRATE your confidence to understand what is helping or hurting it. CONTROL common villains & kryptonite that constantly steal confidence. COMMUNICATE confidence to have true executive presence & leadership influence. COACH yourself & help other people using practical techniques & tools.
