Yep I do this also, but not to the degree you seem to. I prep a short mental list of things I wish to cover (usually compiled throughout the week) and start session with a brief week recap and then move on to the stuff I really want to speak about. T is pretty good at spotting the things which are most important anyhow and if I miss something off my list then I reason that there is always next time and maybe it wasn't that important anyway.
