Limiting beliefs are created by YOU, so that in itself should show you how powerful you are, you have the power to limit yourself and the power to free yourself. Limiting yourself doesn't feel good, and that is because when you limit yourself, you're resisting who you really are (your true nature is infinite freedom and power) That's why everytime you limit yourself, you feel crappy, because deep down you know nothing is wrong, and nothing can keep you from what you want. Deep down you know you are all powerful and 100% free.
Anything that anyone gives attention to, becomes true
