Welcome aboard, Walter.  I'm a 41 yr old dad of 5 and only recently picked the guitar back up (I played it in college for 6 months, but just couldn't commit the time) after a divorce.  It's brought me a lot of pleasure and if you put the work in I'm sure it'll bring you a lot of pleasure too.  Just be patient and confident in yourself and your abilities and I'm sure you'll do great!!!

There's a lot of content here and the instructors are super helpful with their knowledge of the guitar as well as the content on the site.  There's going to be a lot of struggle points so keep raising your hand and asking for thoughts and support, because we all need it.  This is nowhere close to simple.
