When you learn a new lick, if you don't use it, you'll lose it.
That's why when I learn new licks that I want to retain, I make sure to work with them for a while over top of a jam track. I do my best to "break" the lick, dissecting it into smaller pieces, and working with all the chunks. I try playing the lick in a bunch of different tracks, over different rhythms and styles of music. By the time you go through this process, you won't even have to work on remembering the lick - your fingers will do that work for you!
Here's the basic tab for the lick we're working with in today's lesson, however notice that in the video I rarely ever played it this way. That's the whole point - take the basic lick idea, then find new ways to play with it. This really works the creative side of your brain, and it is terrific practice for soloing!

Great idea. I have books with hundreds of guitar licks. This is a good way to memorise the best ones and “repackage” them. Fantastic lesson.
