I've been playing the guitar for nearly 4 years now, entirely self-taught. my practice routine in the 1st year used to be chords and simple songs for about 3 hours a day. 4 days a week. about there la.
2nd year, i discovered scales and how they work in keys. i learnt the pentatonic then. a little about the major and minor scales. learnt the blues, rock and a little metal. learnt how to slide bend and do vibrato. i practiced much more in the 2nd year learning solos and licks, alternate picking ,tapping, legato and palm muting.
in the 3rd year, i had several riffs and techniques down already. i practiced less during this year as i was stagnating. after about 2 months or so. i decided to study modes on my own as nobody around me knew about them or what they were. it took me about 3 months studying and learning how to use them. it was the toughest period. a teacher would have helped alot but i'm cheapskate like that. LOL
From then up till now i've been building up licks for each mode. learning a little sweeps and songs whenever i do a gig. of course theres always the occasional lick or phrase through the years which will catch my ear and i would have no choice but to force myself to learn it because it sounds so damn good. yeah. thats my progress up to date.
Of course there are details i've missed out due to my lack of memory. but basically, effective practice is the way to go. don't linger too long on something you know very well already and keep challenging yourself. thats my theory for improvement.
