Playing around the same licks over and over, happens often when you're not playing with other people, that or jamming and tending to always differ, sure it's cool for prog but sometimes a backbone can't hurt, fixing yourself guidelines are really helpful.

Anyways, are you thinking your playing has attained a certain maximum or something in those lines ? If so try to learn new stuff usually the habits evolve as your experience is, just play varied exercises/songs and the most you play with a band on practice/live the most experience you'll get since these are the true battlefields, your room is a training camp.
