Do you record yourself playing chords and then play along with the recording? I started out doing that. But I did learn a lot of solos from other bands before I just go tired of the weird stuff (well, now that I know how it's done it is a lot cooler) so I just started jammin' with my own recordings and things just went from there. It also helps if you have someone to jam with too, that is IF the other person can allow you to experiment with solos. Just try not to get stuck in a rut. That happens way too often BUT during the creative period you will get much better and cleaner.
