I'm 100% self taught..never had a single real life lesson in my life. I learned by listening to records (in the days when there were no computers let alone you tube etc) and tuition videos . Today there is so much online it's amazing...if I had had access to all that back then I'd be a better player.
New The main problem with learning from websites, books,etc is that you don't have someone sitting in front of you to point out anything you are doing wrong before it becomes a habit. Bad habits are hard change so try and find someone who can play well, that is prepared to keep an eye on your technique.
Totally agree with this...learning alone it's very easy to learn mistakes and not know it.
One of my fav players ever Vinnie Moore once said "Practice does not make perfect, perfect practice makes perfect"
I'd be inclined to have a teacher sit with you to show you the basics...also crucially important stuff like how to tune and properly set up your guitar, how to get the tone you want etc.
There are many of exercises you can then practice...I used Vinnie Moores Hot licks videos at an early stage...moved my on light years.
The single biggest thing though is attitude...I got hooked when I heard Blackmore play, and then when the girls at school all wanted the guys who were in bands..whatever the reason, it must be something that really fires you up...playing is all about the journey, the destination doesnt really exist...there is always something else to learn.
Take each exercice really slowly. GET IT RIGHT, don't rush...speed will come, accuracy is more important. Play along to backing tracks all the time (
www.freeguitar backing tracks.com)...youtube for "how to play ..insert your fav song"
I'll happily help if I can online...been doing this 35 year now...it's part of who I am.
