Happiness is a choice you make and a skill you develop. The mind is just as malleable as the body. We spend so much time and effort trying to change the external world, other people, and our own bodies, all the while accepting ourselves the way we were programmed in our youths. We accept the voice that talks to us in our head all the time as the source of all truth. But all of it is malleable, every day is new, and memory and identity are burdens from the past that prevent us from living freely in the present.
