BTW, here is a super short summary of my stand on free will:
Yes, we have free will but it is much weaker than we imagine or want it to be, and it is not immediate like we want it to be.
This delay in it, and its weakness means it is prone to failure, at first.
BUT with practice and persistence it can grow in strength, like a muscle.
We can't control everything about our brain, but with a few things in it, we can learn to control better tomorrow than we could yesterday.
