"Real change happens from inside out"
It implies to leave behind the person you were in order to become someone else. It's not like changing cars, or houses or countries. It happens inside you and you let go of what made you move forward, your ambitions and priorities. You let go what you felt for others. What was important is not any more. What scared you doesn't anymore.
I realized that my ambitions were not my own. That I pretended to feel what I was supposed to feel for others. When I let go I lift off a huge burden. Just then, when you don't have to pretend you become free.
On the way I had to break some attachments. Let go of an awful amount of anger and hate. I left nothing inside, at the same time nothing is so many things. Love in the wide sense of the word.
