The difference between success and failure often boils down one thing: confidence. If you take two men of equal abilities, with one having confidence and the other lacking, the confident man will be more successful nearly every time. Confidence can propel someone to achieve things that would not have been possible without it. It leads men to hit game-winning shots and home runs. It leads men to plan battles that change the course of history. It leads men to initiate relationships with beautiful women. In short, it allows men to maximize their God-given abilities. On top of that, it makes us happier. A confident man is not always happy, but a happy man is almost always confident.
