Contrary to popular belief, I have a suspicion that self affirmation is a zero sum game.
It simply raises your ego. Affirmation is self referential and circular by its very nature. You strengthen the thought pattern through constant looping of the same or similar thought patterns – building a track of stories in your mind hoping that one day they will give you security once they turn into stone.
But what you find is that the rigidness of mind will only cause more pain.
The other path could be expansion…
Curiosity always brought me the most freedom in life.
