It doesn’t matter what other people think of you because they don’t have to live with you. You are the only person who has to live with you. When you over value what other people think of you it’s because you’re looking for someone else to fill your cup. this is part of the issue that so many people have with over-valuing other people’s opinions.
Believing in yourself means having faith in your own capabilities. It means believing that you CAN do something — that it is within your ability. When you believe in yourself, you can overcome self-doubt and have the confidence to take action and get things done, and not worry about what anyone thinks.
