But the fact of the matter is that we have no choice but to believe in ourselves -- because no one else is going to do it for us.
A lack of self-confidence impairs our ability to land dates, get jobs, build relationships, and -- most important -- enjoy life.
Doubting ourselves can lead to low self-esteem, which can in turn snowball into depression and other more serious health outcomes.
Once it becomes apparent that many of the excuses you concoct for not succeeding are in your head, you come to realize that you've been holding yourself back for no reason at all.
Maybe your parents or peers told you that you couldn't achieve something and brainwashed you against yourself. But how would they know what you're capable of if they're not you?
A person can achieve anything he sets his heart and mind to, but that doesn't come without a few stumbling blocks along the way.
Michael Jordan, who's considered one of the best basketball players ever to play the game, said this:
"I've missed more than 9,000 shots in my career. I've lost nearly 300 games. I've been trusted to take the game winning shot 26 times and have missed. I've failed over and over and over again in my life. And that is why I succeed."
And Thomas Edison, one of the world's most renowned inventors, once quipped, "I have not failed. I've just found 10,000 ways that won't work."
Jordan and Edison illustrate that persistence pays off, and the only way you really fail is by giving up.
Don't give up on your dreams, however big or small. Whether you aim to start your own business, travel around the world, or come up with a cure for a particular disease, anything is possible so long as you work hard and are not paralyzed into inaction by setbacks.
You'd be amazed at what you can achieve when you stay positive and work toward achieve your goals one day at a time.
There's probably someone else in the world who's already achieved what you want to do, or something like it. Ask yourself this: If they could do it, why can't you?
Tap the power and will inside of you to achieve what your heart desires!
