and if you're not "truthful", first -- it is irrelevant whether you believe in yourself or not
because the "crash" is inevitable and it won't be pretty
create, believe, own . . . in that order
be honest with yourself, accept what you find or work to change what "needs changing"
and then move in alignment with that truth
the secret to happiness or the promise of "future" misery
up to you to "decide"
but -- honesty, first and foremost
and then, you MUST own what you find out . . . about who you "truly are"
