Did you know Leonardo Davinci was famous for not having finished his projects? Between being a perfectionist and what many think was attributed to ADHD, he got so hyperfocused on science that he was attacked by many of his peers (and even called a failure by young Michelangelo) for appearing as not having fully accomplished much of his commissioned painting work.
Interesting to hear that. I'm sure some of us can identify with that, right? People claiming we don't finish stuff so why bother, right? Eh- I say "what did you learn from it?" not "what did you accomplish?"
Don't ever think of yourself as a has-been... or a never was. Sometimes the goal is different, and for different reasoning than what others are capable of, or prefer to understand. The road less traveled is often the one that leads to most enjoyment in the end. Kind of like customizing a sandwich to your tastes. What if you don't like the default choices? You never ask yourself "what does everyone else like?" you just simply say "I want this..and that...."
