Stop sharpening your tools and just use them for a while to do something fun or interesting. Different parts of your brain are trained by different activities: study, play, taking tests, competing, working with other people, fighting for your life, etc. You've probably done the equivalent of an athlete who spends all of his time on drilling certain basics without spending much time actually playing the game. Go play the game. Put projects before skills for a while and your skills will improve, too.
