I am still working on getting the fingers toughened up and working on the perfect “D” chord. I’ve fooled around with changing to the “A” chord but still pretty much just waiting for the callouses. Years ago, I tried to rush things and never got anywhere. I’ve realized by reading different discussions and just plain living long enough that the two key things are practice, practice, practice and patience, patience, patience! I’ll be back when the fingertips get tough!
