Fair play to the 15 yo! If I was playing when I was 15, I'd be chuffed if I could play Yng licks......
No need to rip him - that's the problem with text, there's no emotion.....we just read it and if we read it as egotistical then damn him to hell!
Anyway - onto the point....I used to practice all of the time and after a while I didn't really see any improvement. Anyway, after 4 years, I basically ignoed guitar and played semi-pro football (soccer) for eight years.....
I've packed that in and two years ago I picked up my guitar and joined a band......didn't work out, no gigs etc. So the singer and I formed a covers band. We now play every Saturday, most Fridays, some Sundays and some Thursdays.
In the six months we have been doing this - my playing has improved 10fold.....phrasing, speed, clean-ness of legato, having to use pentatonics, blues scales (which out of principle I would never use)....hell even my singing......
....and my point - get out there and join a band and play live....you'll learn a hell of a lot more than sitting in a bedroom!

(and the sights are better......last Wednesday, a girl 'popped out' of her lace top whilst dancing, and on Friday another girl flashed us her g-string!)
