I agree with you absolutely! I enjoyed reading this because you nailed it!
When you think about a goal of being unaccomplishable, then it becomes unaccomplishable, when you see a goal as a success even before you start, it tends to become a success.
You are right, life is a chain of self fulfilling prophecies...you can be 'it' if you can envision 'it' into existence. Beautiful motivation @gbenga
