Fake it ’til you make it. Ever heard that phrase?
If you want to be more confident, feel more confident. When you find yourself feeling nervous and unsure, stop for a moment, close your eyes, and think of a time when you felt confident and self-assured. Use all of your senses to bring you back to that moment. In doing this, you’ll be more able to cultivate that feeling in the present moment.
Also, consider your posture. Choose a body posture that looks and feels confident. Next, think about your clothing and style. Dress to impress—yourself! Dress in a way that makes you feel good. If you look good to you, you’ll feel good, and feeling good often leads to higher self-confidence.
