When you believe in yourself, you tear down those limits. Achievement is your duty, your responsibility, and your obligation. When sharing your dreams and goals, you have to forget and let go of what other people think or tell you; It's your mind talking, not theirs, listen to yourself.
You are not stuck, unable or without talents. To learn and know more, you can read a book, take a class and then move on to the next, because you are not a victim of your circumstances. You have to decide if the only limit is you. Therefore, make a conscious choice to move the needle in an area of your life that has been frustrating you.
The Limit Begins In Your Mind
To get rid of any limit, you must establish in your mind that what you want is stronger than anything else you want. Then, you have to burn the bridges behind you and say once and for all that this is all.
