Before you walk into that job interview there are some ways you can practice acting more confident. Often the skills needed for a successful job interview are closer to that of a salesman or actor rather than the job you’re interviewing for. Introverts may need to do a few out of the box exercises to boost up their energy and confidence. First, visualize yourself as an outgoing confident person. Go to the grocery store as an outgoing person and start chatting with the checkout person about the dinner your making. Rinse and repeat. (At the library, business event, class, etc). Spend some time walking in those shoes, in whatever way you can. The “fake it till you make it” adage really is true. Confidence is a muscle. Even if you start out weak, working that courage muscle will make you stronger.
In this TED video Social psychologist Amy Cuddy shows how standing in a posture of confidence, even when we don’t feel confident — can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.
