I think the adaptability that's sewn into our fabric as humans allows us to be malleable in that way to be able to feel fear and embrace it, to be uncomfortable in order to be comfortable.
That feeling is so foreign, and yet when you do embrace it, sometimes it'll throw the mantra off and lead to Self Sabotage and falling back into habits you tried so hard to break and grow from.
It's similar patterns we go through, and it really puts us in a position to test if we're really transitioning from an outgrown version of ourselves and learning from our old habits and trying to break them.
