Replace negative thoughts like "I can’t do this" with more constructive ones like "I’m capable, and I will improve."
Break larger tasks into smaller goals. For instance, if you're aiming to improve public speaking, start by practicing in front of a mirror, then to a small group of friends.
Make a list of your strengths and reflect on them daily. Engage in activities that allow you to use and improve these strengths.
Before important events, like a presentation or meeting, stand in a "power pose" (e.g., standing tall with hands on hips) for a few minutes.
Spend a few minutes each day visualizing yourself succeeding in situations where you want to be more confident, such as interviews or social settings.
