To me the terms mix and it helps to separate the things that are externally manageable from the things that are not. The physical is complex but straightforward - the body biochemistry operates on material in, biochemistry mix, expenditure out. The brain is physical - neurons, pathways, etc. The mind, OTOH, is a virtual little candle isolated in a prison of meat and bone trying to understand how to interact with the world around it. External forces can alter the body and brain, but only the mind can change the mind. And does, in ways that are very difficult to control because the sole operator is part of the mechanism. People who try to change on their own and can't aren't failing or weak, it's just really f-ing hard.
