This concept can be applied towards many things in life.
"The one you feed."
It may be good vs. bad. It may be focusing upon what you can do vs. what you cannot do. It may be focusing upon your personal losses vs. what you have. The list can go on and on. It's your attitude towards life.
Within the context of autism, one of the "low dopamine" neurologic conditions, there is a tendency towards depression. With that, some degree of wallowing in self-pity and focusing upon all the bad things in your life, how life has somehow wronged you. When, for many of us, there are things that we can do that may appear to others as special aptitudes or even "gifts" that we may or may not be taking advantage of. It's all about the attitude towards life and choosing what "you feed".
Just a life story here:
Many years ago I was invited to participate in a local powerlifting competition. Three lifts, the deadlift, the squat, and the bench press. Then, I noticed they separated out competitors into classes, by age, gender, no assistance gear (raw) or with gear, tested (clean) or non-tested (performance enhancing drugs). As I am watching and competing, I quickly realized what wasn't there. A special class for people with physical disabilities. So, I am watching an elderly man that had so much arthritis he couldn't wrap his hands around the bar,...doing deadlifts,...with a lot of weight. I watched a person roll up in a wheel chair, paraplegic hop up onto the bench and press over 500lbs off his chest...and won his class amongst other "able bodied" competitors. I watched a person with an artificial leg do deadlifts. I was amazed, but then I kept hearing the mantra of the powerlifter,..."Do not focus upon what you can't do, but rather what you can." If you tear a bicep tendon or pectoralis muscle,...just move onto your leg workout,...don't wallow in what you can't do.
