I've been programming for about 40 years. Had ups and downs. But I mostly worked on creating new products (not always purely software). Also been on my own for the most part. In the end. I love it and I hate it. I love it because it let me express myself and it is a great feeling when you see others using your products. I hate it because there is always way too much non creative work and general BS around but that's life.

But generally I enjoy it and are not planning retirement. Will just maybe work less.
