There is however an element of inauthenticity to this statement, as it implies faking or acting like you know what you're doing when you don't. Also, in my humble opinion, you've already made it if you've mustered the courage to try something new, scary and thrilling.
So, during my coaching session this week where I was the client (yes, even professional life coaches hire life coaches when they are in transition or looking to achieve new and exciting goals. Think of the Einstein quote: no problem can be solved from the same level of consciousness that created it. Therefore my business/ life coach is my personal brilliant brainstorming strategist, who offers fresh perspective to my habitual ways of thinking and doing things) My coach helped me to reframe the old "fake it til you make it" into a phrase that feels much more true to who I am. The new statement is: As I do, I become. Isn't that a great sentence! You too can put this into practice. So you want to become an artist? Begin painting and you are becoming. Want to be a writer? Then write, and you are a writer. So you would like to be a dancer? Find an online tutorial and know that you are becoming a dancer with every fumbled step taken. The concept is so simple, and yet we get fixated on the end result, feel overwhelmed and we don't get started on the becoming that will make our heart soar.
There are so many resources online that can teach us how to become anything that we desire, if only we took that first step in becoming. Forget the destination and start living for the becoming, that's the place where the excitement magic and joy reside.
