"A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms agains himself. He makes his failure certain by himself being the first person to be convinced of it"

This quote by Ambrose Bierce talks to the power of self-doubt. When a person doubts themselves, it resembles they are employing in the ranks of their opponents and fighting against themselves. This insecurity can be extremely damaging, as it can lead to a person believing that they are not capable of accomplishing their objectives. This can lead to a person quiting before they even attempt, making failure a certainty. This quote works as a reminder to not let insecurity take control of and to believe oneself. It is essential to keep in mind that everyone has the possible to be successful, and that insecurity should not be allowed to stand in the way of achieving one's objectives.
