Great thread, loved reading everyone’s stories! 
Mine is as follows…
Always had music in the house growing up, lots of Stones, Queen, Beatles, 60’s rock & pop (mum); country & western (Dad); but they were non-musical parents from an instrument playing perspective.
I loved hard rock and heavy metal from an early age, and was especially in awe of the guitarists.
Up to about when I was 12, Angus Young was my hero, then it became Jeff Hanneman/Kerry King (Slayer), James Hetfield/Kirk Hammett (Metallica) and Dave Murray/Adrian Smith (Iron Maiden). 
When grunge hit, Cobain was also huge influence along with Dave Navarro (Jane’s Addiction) and Tom Morello (RATM).
Around this time I was given an acoustic by my parents at 14 (still have it) and had some lessons. Unfortunately the tutor was into easy listening/country so the songs he wanted me to play I wasn’t into at the time (would certainly appreciate them more now! 
) plus at about lesson 4 he wanted me to start singing along and I certainly wasn’t into that at 14! 
So as any good teenage would, I quit of course… (so many regrets!! 
)
Kept the guitar with me through the rest of my teens, into my twenties and thirties. Learned a few basic tunes and riffs along the way when motivation came but mostly it sat in the closet…
Then when about 40, I decided I’d messed around enough and started to get more focused, began playing a borrowed electric from a friend, then brought my own, then another… and another…
Justin had been on my radar for a long time, having seen his song tutorials and lessons on YouTube but I hadn’t fully committed to that until last year when I realised I definitely needed more structure and to get to grips with the basic concepts that I’d glossed over along the way! Justin has been a real game changer for me as I know he has for many others too.
So these days I am fully immersed into learning guitar, following Justin’s course (grade 3 currently), improving (albeit slowly) and loving every minute of it!
