I would suggest you check out Troy Grady [1]. I've been playing the guitar on-and-off for 33 years, and most of the 'off' has been because I've reached a hard limit for picking speed; my left hand has always been pretty good, but right hand and high-speed synchronisation has always been a problem, and I never fixed it, just got frustrated, stopped and then started again. While I teach for a living now, it wasn't until I saw what Troy Grady has analysed and offered that I started practicing properly again after years of neglect. While I have a LOT of work to do to get my right hand sorted, after a few months I'm starting to see glimpses of improvements, and being able to pick well.
If you're of my age (I'm similar age to Troy Grady, 45), then the free cracking the code videos on YouTube are a good watch anyway - entertaining as well as the story of playing guitar that I largely paralleled (but never found the solution that he did, alas, until now).
