You must do the thing you think you cannot do.
Eleanor Roosevelt has some of the greatest quotes and insights out there. You have to admire the simplicity and directness of this quote. You simply must do the thing that you think you cannot do. What the quote does not say, but you can infer, is that once you’ve done that one thing, you should move on to the next one and conquer that as well. As an achiever, you must learn how to confront and overcome your fears, and you must do so on an ongoing basis. You will find that once you develop that mindset, it will become a very valuable habit that you can deploy in every aspect of your life.
