This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

I've been playing guitar for over 30 years. I never took formal lessons - only ocassional ones targeted to a specific topic. I love the discovery process and the relationship I've created with the instrument.
Five years ago or so, I had an a-ha moment, which fundamentaly changed the way I approach my learning of the guitar. After internalizing all the content I consumed, I thing I've come up with a formula for learning both rhythm and lead guitar in a very streamlined and systematic fashion. This method will teach you how to find chords across the entire fretboard so you can create chord progresssions for your own songs, or to make it easier to figure out the chords of your favorite songs.
