A lot of people will tell you that you need to drill down with 8th notes and a metronome until you just want to barf.
Others might think that after four years, if your progress has stalled to the point of frustration and second-guessing yourself, it might be time to roll up a doob, jam out to something completely different, and start trying to develop a style that incorporates your unique idiosyncrasies. It doesn't sound like you are in a band, so don't sweat it. I would say it took me 11 years to not be somewhat ashamed of my playing.
