Hey Old 'n Slow, you are worthy! The time is now! Especially in light of Brenda's concept of getting "a Christmas present for myself"-- I must say I really like that concept! And Brenda, that's a beautiful instrument and beautiful playing!
Old ‘n Slow Bill makes a very good point about the time is now. If you love to play and it brings you joy then you are worthy. That is the only criteria, if playing skill was one I certainly won’t be worthy of any of my instruments. Fortunately there is no “Standardized Ukulele Examine” we have to pass to graduate up to the nice stuff.
If you are breathing you qualify. You will be dead for a very long time so enjoy life now while you can.
