Personally, that wasnt obvious to me to for quite a while. I assumed once I was playing fast and playing Megadeths Rust in Peace album from start to finish with every solo, I would be writing just as well. That it would just happen naturally.
But nope, I got exactly what I practiced for, nothing more. And I just wanted beginners to know to not make the same mistake.
I'm sure others have ran straight into the same brick wall that I did...?
