Have you ever seen someone who didn't buy a car because he failed to learn how to drive? Or have you ever met someone who tried to learn how to drive then decided not to try again after failing for few times?
Personally, I have never met anyone like that. Almost everyone who starts learning how to drive ends up being able to drive well. Although not everyone becomes a driving expert still everyone who tires learns the basics of this complex skill.
The question is, why you succeeded in learning how to drive yet failed in achieving some of your other goals?
The answer is simple: because you were sure that you were going to be able to drive long before you sat in the driver's seat. You saw everyone around you succeeding in doing it and so were convinced that there's nothing particularly hard about it, even though it really is a complicated skill.
Believe in Yourself and People Will Be Forced to Believe in You
Billions of people fail to live the life they have always wished to live. They fail to realize their ambitions and give up on their big dreams as soon as they encounter the first obstacle. One of the strongest causes for this attitude is that they do not believe in themselves.
Believing in yourself is all about being sure that you are going to do whatever you want even if others were against you. Usually, when you decide to take a big challenge or to do something that people failed to do you will find that everyone is putting you down.
Under the pressure of this criticism some people start to doubt their own abilities and eventually give up. The few people who manage to believe in themselves and who continue moving along the path they've chosen are the ones who succeed.
