Learning new tricks for this old dog is hard but I'm hanging in there until I get it.A trick I learned a long time ago is called "space repitition". In other words, do it over and over until you get it. This training by WA is very well done. When I get frustrated, I take a break, read or watch it over again and then try it again until I understand it. Don't let the lesson's being hard to understand stop you. The understanding will come and the results will be worth it.
