I've always found guitar contests especially online ones are a great motivator. This one closes to entries very soon but even if you don't entry you can jam over the backing tracks and vote for your favourite entries. Here is my entry. Detail on the contest, sample tracks and the backing tracks can be found here. http://www.epiphone.com/Contests/2015/Jim-Oblon-Video-Challenge.aspx
Ok just read the rules and realized I've gotta play my Epi so here is another take over a different backing track. Cheers.
