“Reality is merely an illusion, albeit a very persistent one.”
-Albert Einstein, US (German-born) physicist (1879 – 1955)
Remember that your beliefs and convictions are the result of your own individual life experiences. Your limitations grow from those experiences, and are reinforced each time you identify something that fits in with your belief system.
Anytime you catch yourself saying “I could never do that,” take the time to consider why that’s the case. Is it really true, or does that belief simply ring true given your past experiences? Can other people do it? If so, how are those people different from you?
Recognize the difference between the words can’t and won’t. Ask yourself the question: Are you are really incapable, or just unwilling?
