How does one's self-confidence help someone achieve their goals and dreams?

Question

anonymous · Answer

Self-confidence allows for the dreams and goals to be entertained in the first place. You need to be able to believe that you can accomplish something in order to envision it as a goal and come up with a plan to get there. Without self-confidence, you won't feel capable or smart or strong enough to reach your dreams and goals. Without it, you might not even start saying "here are my goals" because you don't believe you would be able to achieve them.

Your self-confidence is your trust in your own skills, your ablilities, talents and latent potential. It's literally being able to say to yourself..."I trust myself with this goal/task/dream and I trust that I can accomplish this." It's that simple. That's why most goal setting/self help authors say to work on small tasks leading to a bigger goal, more often that not we trust ourselves with little steps along the way.
Most people I've seen that set down a goal of some sort, they most often fail because they ultimately don't trust themselves, they don't believe in who they are and what they're capable of. Being able to trust in yourself is based on your emotional and behavioral needs and if they've been met or not. 
You have to trust yourself, be honest with yourself, know that the goal your setting is yours (not someone elses) and if you find yourself making confident decisions, then you're most likely developing your self-confidence.

Self-confidence is very important. If someone wants something really bad, it'll be ten times harder for them to get it if they are saying to themselves "I can't do this." Sometimes a person's self-confidence can be destroyed by other people. When other people say "You can't do it," the person may start to believe them over time and begin giving up. But the best thing to do is to ignore people and keep a hold on your self confidence. Saying "I know I can do this." will make acheiving a goal a whole lot easier because you will be motivated.
