Self-doubt is a given, normal and ordinary. But, self-doubt can be a persistent obstacle, unfortunately. It’s that voice inside that questions your abilities and worth. But it's important to remember that everyone experiences self-doubt. The key is not letting it control you. When self-doubt creeps in, acknowledge it, but don’t let it dictate your actions. Challenge those negative thoughts with evidence of your past successes. Surround yourself with supportive people who believe in you. And most importantly, be kind to yourself.
