Who you really are, your True Nature, is no more tied to the kind of person you've been than the wind is tied to the skies through which it moves. Your past is just that, the past, a place within your psyche with no more reality to it than a picture of a castle on a postcard is made from stone. You have a destination far beyond where you find yourself standing today.
Learn to be one with who you are in Reality, and the waves of a thousand passing worlds cannot wash you away.
Do the moment-to-moment work of dropping anything that wants to drag you down, and Reality itself will see to it that you rise.
The only world in which "defeat" exists as a reality is the one darkened by the false idea that what may have happened to us a moment ago is the same as what's possible for us to achieve now.
Your past is just that, the past, a place within your psyche with no more reality to it then the picture of a castle on a postcard is made from stone.
The deepest parts of you know that if freedom from fear was as easy as 'creating a new reality' for yourself, then you would already be the fearless person you know in your heart that you're meant to be.
