Yes, it could be you need even smaller steps. So when you put your materials out, leave them and come back later for the next step,and then only open the materials to the place you need to begin, and leave for awhile again.
If you have more time than something day to day, take a few days in-between steps..or weeks even! While you do each step, remind yourself (over and over if you have to) that you are only doing this one thing, and then you'll leave it for a while.
