This honestly doesn't make much sense to me. If you have to push to get your words out, then that is a specific trait of the way you stutter and the effort you need to put in to break a block. You push in other to get through the block as you stutter, but doing so means you don't accept it? What is the alternative? By that logic you would have to just shut up and no longer talk the moment you block on a word in order to accept it. Besides that, accepting it doesn't really relate to the physical aspect at all for me. For me it is seeking fluency while at the same time accepting that I'll probably never 100% get there. It also means accepting that some people will always judge me and that, to some degree, I have little control over when and where I stutter. The most important consequence from this is that it's not my fault if it doesn't work out perfectly. So I put in the effort I can at any given time and don't blame myself if someone judges me or it doesn't work out the way I want it to.
