Hi Dafka1,

Congrats on your progress so far!

It is totally normal for the learning process to flow along nicely at times, and at other times feel stalled out. Progress is not ever a steady straight upwards line. 

Since you are wanting to learn to play great solos, once you get through Fundamentals, you'll want to pay particular attention to lessons on the use of the Pentatonic Scale. That is the "secret weapon" that many great soloists start with.

Have fun!
