Been playing Guitar and Banjo now for over 60 years and still regard myself as always learning. Old age and arthritis is restricting my playing these days so I try and play songs or tunes which only need easy chords. The banjo is a great instrument for this as it is tuned in an open chord, though, I suppose you could do this with the guitar.
The important thing is to keep playing and to pass on what you can. I am fortunate to have 2 sons who are both fine musicians and often help me to transpose into easier keys.
