Tips are great. They're short and give quick instructions. Nobody says they'll work for all people on the spectrum, but they are just things to give a try to. Unlike many highly expensive programs, most tips involve no cost at all and my text books in particular are full of such tips because many of the things that have helped me most were either cheap or free. People think solutions have to come in an expensive training package and a team on ones doorstep with clipboards but for me, much of the things that worked best each contributed their own 10% improvements which together added up to more than 10% when they all came together. We are multifaceted human beings and often solutions are just as multifaceted.
