Maybe its time to learn some new chords??? Or maybe learn to barre some that you'd been half barring,try laying some lead down over songs you've only been chording, or put some fill in strumming on lead parts you know. Maybe its time to take those 'slow' solos up a notch, learn something on the same level that has a faster tempo, or start breaking down longer solos? MAYBE its time to expand your musical horizons by studying a new style of playing.
Its really all up to you. The good thing is that even when we think we've hit a wall, there's actually a whole 'nother world of playing just beyond our sight. All we need is that one little inspirational 'breakthrough', something so obvious that we'll look back after we've mastered it and go 'My God I can't believe I didn't know how to do this." I'll never forget the day I figgered out I could actually bend the strings lol
SO, what do you do untill the breakthrough comes??? You keep playing, pushing yourself to play new things, and when you encounter something you don't know how to do, its time to learn how. Hit the books, ask advice, look up lessons, whatever you have to do. AND KEEP PERFECTING WHAT YOU ALREADY KNOW HOW TO DO, each level of playing acts as a base board to the next, what you master today might be the underlying principle of a new trick,riff,lick, or even picking style, strumming pattern etc.
Its kind of like algebra, except you'll want to do it.
I have to say your learning very fast by the way
