I may be the 'old man' here. I am 70 and have been playing for a few months. Just about to finish the 2nd set beginner lessons. I'm fairly comfortable with my 'cowboy' chords. I have found that using my phone and video recording myself has helped a lot. It has shown me just how bad my singing is! ;-) Once recorded, I upload the videos to YouTube (private, of course). Then, I can watch them at any time from anywhere and critique myself. I am far enough in the course now to know how barre chords are formed and I am kind of excited to be able to work on them. Practice does not make perfect, it makes permanent. So I have to be careful to take my time and do it right and don't program my hands and brain to do it wrong.
