Integrity is to say what you mean, and do what you say. It is to be the same person everywhere, and to all people.
Integration (as it pertains to psychology) is the process of joining together different parts of the self into one unified whole.
It’s been my experience that one leads to the other, and vice versa. It’s also been my experience that one is not even really possible without the other.
So, if integrity seems hard, maybe it’s time to start thinking about how to become better integrated. And if you’re not sure how to do that, it could be helpful to practice better integrity.
They both lead to the same place, which is where you want to go.
