I’m about a month and a half into “30 Days to Play.” I'm a 75 y/o retired surgeon with arthritic fingers (like they say about cars: it’s not the years, it’s the mileage), so it’s slow going. Currently struggling with the dreaded F chord. But I’m loving it. Your approach to learning is spot on (short sessions, consistently every day). The first few weeks were a little bumpy, but now that it’s become part of my daily routine, most days I can’t wait to pick up the guitar.
