As cliche as this may sound, entrepreneurs build success by learning to believe in themselves. Self-doubt can hold you back and prevent you from achieving your full potential. This holds true not just in the world of entrepreneurship but across all career fields.
If you don’t believe in yourself, you’re going to put too much importance on all the hurdles along the way. So you could find yourself holding back from executing an idea that has high chances of success just because of negative feedback or a challenge. If Mark Zuckerberg had listened to naysayers, we probably won’t have Facebook today.
