Answer: Because when you believe in yourself, you can overcome self-doubt and have the confidence to take action and get things done. When you're drowning in fears, doubts, and self-sabotaging behaviors, success feels out of your grasp. All of the skills, training, and tools in the world won't change your life.
Why believing in yourself is so important: A strong belief in yourself can bring you all these benefits and more: You recognise your ability to accomplish goals
