In the journey of life, doubt can often be the biggest obstacle standing in the way of our success and happiness. It is a universal human experience to doubt ourselves at some point in our lives. But why do we as humans doubt ourselves? Understanding the roots of our self-doubt is the first step in overcoming it. One of the main reasons we doubt ourselves is fear. Fear of failure, fear of rejection, fear of not being good enough - these fears can paralyze us and prevent us from taking risks or pursuing our dreams.
