following this course will probably help you but the problem with most courses is that the are structured in a linear way. That means you master 1 item (for example sweep picking) in lets say to months. After that you go for the second item and so on.
The problem is that every time you master one thing you are a complete beginner at another topic.
What you wan't to do is focus on more items at a time.
Here is an example of such a shedule:
5 min. warm up
15 min. scale sequences
15 min. arpeggios
20 min. improvisation
10 min. strumming
....
This might be common sense but it is a thing that also got me struggling for quite some time.
also you don't have to do every thing every day search like every week or so for your weakest point and focus a little bit more but not entierly on that.
I don't say that this course is bad but you have to use it in the right way :)
good luck and keep practicing.
