Let me add Al Brisco as an inspiration.
I feel, how many can aspire to be exactly like Malmsteen or Oscar Petersen, Keith Emerson?
If you can soothe your soul getting any level of proficiency, it was worth the journey. If not keep at it till it happens one day and you may just even get a fleeting glimpse of joy. Even our heroes have their ups and downs.
I like the ability to say something within a song that pulls at your heartstrings. It could be something simple like Dahl's
Help Me Make It. or on Tim Mcgraw's
Better Than I Used To Be which if I'm not mistaken is Dan Dugmore.
For myself, if I hear something in my head, try to get it out through your hands and feet. If we try and play what others thought up only, we are not being ourselves, we are trying to be them. Yes steal a little, channel a bit, but then add a whole lot of yourself in there as well.
Watch how Zane King emotes what he hears in his head. I wouldn't doubt Zane has an extra pedal or lever that attaches to your heart. He's definitely "being there."

Recording yourself and listening back is key for improvement.
