My life got infinitely easier when I realized the normal way of doing things will never work for me. Even with medication, my brain is too broken to have discipline. I can’t form new habits by repeatedly doing something. Flat out doesn’t work.
What has worked for me is getting ahead of my brain and setting myself up for success before it gets there.
I’ve also completely given up on the idea of thinking before speaking. My solution for this is anticipating mistakes before I get into a conversation and not making the same mistake twice.
