I would think that most of our self-limitations are easily identified as helpful or harmful; We can decide which we want to keep and which we want to discard.
Take a moment to think about your own perceived limitations. What do you believe you can’t do yet? What do you believe you’ll NEVER be able to do? Why do you think so?
Once you’ve identified as many of your limiting beliefs as you can; take a closer look at them. Are any of them hopelessly impossible, or do they just feel that way? Have other people been able to accomplish something that you want to accomplish? Have you accomplished anything in the past that was difficult? How did you overcome the obstacles you faced? Could you apply the same process to any goal?
