If I stumbled over a chord when I was playing piano, I started again from the beginning. I took them for granted, thinking that in life I would always have a second chance. Unfortunately, we can't often claim do-overs as we get older. I made some decisions that weren't smart, and they had their consequences. So I have to take a different approach. I have to accept that the past is past, and the only thing I have control over are my actions going forward.
