I was just mulling this over in my head compared to my guitar playing experience.
I am self-taught (some friends helped) and have played for just over 20 years.
I'm assuming here that you are not trying to learn classical guitar, if you are I think you should find a real teacher. I urge you to learn rock music by playing songs. I was an indie rock fan, and started off strumming the chords to my favourite songs. It is relatively easy to do, and the rewards come quickly. The trick is to find a song you like that uses simple open chords, and not too many of them! My first tune was 'Live Forever by Oasis' as an example (cringe). For something more tasteful try 'knocking on heaven's door' by Dylan. It is easy to read chord diagrams. Get a few thin picks and go for it. Really just go for it, the changes will speed up by themselves and the strumming patterns will too, by listening to the song and imitating. Now pick another song with some of the sme chords. A month of evenings can get you reasonably proficient. If you have a friend who is a bit further along then play with them Whenever you can. This is about as far as lots of famous musicians ever got. Remember that!
Alongside this you can try out some riffs. 'Smoke on the water' is the classic, but go with what you enjoy. Tab for these is free online and easy to read. Find a riff you like, if you have a friend who can play the chords while you riff that is fun. You learn riffs like the guy in the article, note by note.
Learning to solo is harder. I used to buy tab books and copy solos I liked. Eventually I realised that I needed to understand some very basic theory, like 'Keys' and 'scales'. I read this in a book but you can google. This is easy on a guitar because you only have to learn a scale shape once and you can change key by playing it in different places on the neck. If you like blues and rock and roll then you only need to learn the minor pentatonic scale to begin with. These 5 notes made many a solo. By running through those 5 notes you start to form licks and phrases you can use. The best way to learn this is to learn to play a basic 12 bar blues shuffle, and play with a friend, taking it in turns to solo. The second best way is a looper or backing track.
I then wanted to play folk fingerstyle. I found the tab for Nick Drake's 'Cello Song' in a magazine and spent a year repeating the first main phrase over and over, a few times most days. The rest of the song came exactly like the op and quite quickly. Afterwards I could pick up other fingerstlye songs quite quickly.
I don't know how to play Jazz.
I think the cap this way of learning places on you is that you don't learn much theory, which makes it hard to arrange songs, compose, etc. Just remember that a lot of the people you are listening to are in the same boat...
