“The people who are crazy enough to think they can change the world are the ones who do.”
Self-confidence is the belief in your ability to accomplish the task at hand. That doesn’t mean being deluded that you can do impossible things. Self-confidence is a belief that you can do something beyond your current level of experience and skill. It’s also having faith that you can handle adversity, and even if it doesn’t turn out exactly as you had hoped, you know you did your best.
Another advantage of believing in yourself is that it can lead to a better quality of life. Research shows that confidence is related to better mental and physical health, higher educational achievement, improved literacy, lower drop-out rates and better economic standing. If you have self-confidence, you are more likely to attend a better school, get a better job and lead a better life.
In fact, there is significant evidence that self-confidence is a more important factor in determining success than talent is. Although confident people aren’t any taller, smarter, better-looking or richer than you or me, they have is a belief in themselves, which anyone can develop.
Believing in yourself and self-confidence are more important factors in determining success than talent or ability alone.
Most people view self-confidence as an inborn quality that someone either has or doesn’t have. Nothing could be further from the truth. Self-confidence is a skill that anyone can learn.
Putting yourself in situations where you overcome challenges or obstacles—over and over again, even if they are relatively small—can develop the skill of self-confidence.
You don’t need to win a national championship or to be elected class president. You just need to do something that challenges you. Maybe it’s volunteering as an assistant so you can learn from the best, getting back into the job market after you have been fired, or sending your manuscript in again after ten rejections and having it be accepted.
