I'm starting to feel as if I have early-onset dementia, because I'll sit down, learn a couple 'licks', for example from a TrueFire "50 licks" course, and then a week later completely forget them. Hell, the next *day* completely forget them. I realize the idea is to incorporate the new material into ones playing, changing, adapting, experimenting...but maybe ONE lick out of many will 'stick,' and I find myself -- when playing -- reverting back to the same handful of licks I've known for years. Any tips on improving the knowledge bank? Is this even a worthwhile approach? It certainly seems that something I come up with on my own sticks a lot better, although it's crude stuff.
