Just my thoughts on this question.
To me it's like " how long is a piece of string "
I think you've gotta ask yourself what you actually want to do/learn.
My journey thus far is slow going but already mentioned about the Anders quote
" Make sure you have fun"
I wanted to learn lead guitar when I 1st joined this site, although thats still a goal of mine , I've since learned a ton of songs that I can play all the way through with chords.
Unless you have unlimited time each day, you have to have a practice routine of what you want to concentrate on.
Sorry for long post
