Sounds like most of the people I've taught...The truth is, most people don't practice in between lessons...I've found that people have this weird attitude that somehow I'm gonna do all the work for them because they are paying me. I just give them the brush and paints, it's up to them whether they paint the fucking picture but they just don't get it. There is a lot of brain power involved, not just the sore fingers bit...I think that's where most people fail. I'm mostly self taught, but everything I've ever learned I've sussed out where it's place is in the scheme of things....Just listening and recognising stuff is a big part of it. Certain triplets are used by near enough any guitar player, all with subtle differences, but try as I might, most people can't seem to take it on board. If you want to learn a few chords, buy a book or go on You Tube... There was a thread on here years ago where I explained that if you learn just three or four chords played in the same sequence just with slight rhythmic differences, then you have the keys to thousands of songs...But people still think it is some great mystery...It ain't, you've just got to put the work in.
