Suspend Disbelief

Act as if your success is CERTAIN.

Instead of holding yourself back because you don't have 'hard proof' that you can make a giant leap forward, see if you can find evidence proving you can't.  Make that giant leap forward and act as if your success is guaranteed.  Then see which set of ideas you should believe in going forward.

Your current mindset may be flawed by doubt and skepticism.  That idea of making an exponential leap in your performance, life, etc--jumping from your present level of achievement to one several stages greater in one bold move--might be a foreign idea to you.  You might not be trained to think in that way.  You may have definite reservations about the possibility that you can make an exponential improvement at all, particularly with less effort and in a shortened time frame.

Experts generally agree that people typically only use about 10% of their true potential.  If we accept that argument, and even if there were no other resources to assist you, you would still be doing ten times better than you were previously.

Your doubts are not the product of accurate thinking, but habitual thinking.  Years ago you may have accepted flawed conclusions as correct, began to live your life as if those warped ideas about your potential were true, and ceased making some of the bold moves you may done as a child.  Find the faith you had in yourself before.

Put old inhibiting ideas to the test by going for your dream with everything you have.  For now, just suspend disbelief.  Suspend any disbelief you have in yourself.  You don't have to be convinced that you can succeed in making that giant leap forward, but you do need to stop believing the old ideas you may be carrying around about your personal limits.

Act as if you have complete faith.  Do what you'd do if you knew you were going to succeed.  Behave with total conviction.

Doubt is what does the most damage to anyone--don't give it any mental space.  Proceed boldly, as if you won't experience anything other than a successful leap forward.

If you must doubt something, DOUBT YOUR LIMITS.
