Use positive affirmations to reinforce your visualization. Repeat affirmations in present tense, such as “I am confident and capable,” “I am confident and clear when speaking in public,” or “I trust in my ability to handle whatever comes my way.” The more personal they are, the better. Then, repeat them on a regular basis, ideally multiple times a day. You can say them out loud, write them down, or repeat them silently to yourself.
