@Sharon_Thoms there is a parallel thread here.
(Many others if you search from the last few months but please don’t feel like you have to look at them all. There are so many, you might not get back to learning 
but skim through them if you have time, because they would have similar information, and you might find a link or information that might help for where you are at the time. )
For me, learning a new “thing” I always jot down notes (on paper) as it is quite overwhelming learning something new and all the associated information related to what might be just one thing, but you then have to read around a few other related topics to make any progress.
