Listening to it now... good stuff.
A few thoughts, which I'll preface by saying I'm a quitter by nature. I'm impatient and I never think I'm "good enough" - I have perfectionist tendencies and I'm really hard on myself. In my far younger years, I quit: school (high school dropout!), piano, guitar, voice, ballet, and writing. And ukulele, my first instrument when I was a small child, although that was more due to life circumstances changing than a conscious decision to quit.
I picked up the uke in my mid-40s almost as a joke - I saw Janet Klein perform and thought "Hey, I could do that!" - I fully expected to never do anything beyond take an 8-week class and strum a few chords and play a few standards. Somewhere in those first 8 weeks I discovered John King and was absolutely amazed, since I had no idea a ukulele could do that. And somewhere in those first 8 weeks I discovered that I could start from almost zero - I remembered very little from childhood music studies - and see measurable progress on a regular basis. Those 8 weeks ended, I signed up for another 8 weeks, then private lessons, and - here I am nearly 6 years later, still at it.
I think for me, measurable progress is the key thing. I don't need to be perfect, I don't need to be the best, I just need to know that I'm getting better. And I am, because I work at it - and this is the element that was missing from my younger years, and I think is missing from others who start enthusiastically then quit. Going to lessons or classes in and of itself isn't enough - you have to do the work! And if you're lucky, like me - unlike my job, with ukulele the "work" doesn't feel like work at all.
