You could do all the planning in the world on which string to start or what technique to finish with, but you're solos arent gonna be anything without an idea and melody in your head and then puttin it into action, what i found that helped me is I hear what i want to do in my head and then try to put it down on guitar. Sometimes a wide vibrato and some slides will make all the difference rather than sweepin here, doin scale runs there, ya know. In my experience having an idea in your head will get you a lot farther than trying to force a solo.
