I am right there with you. Once I hit 80, my powers of concentration waned. As an author, I've started many novels, yet only two have been published to date. Don't give in to the Sloth Syndrome. As Admiral Akbar said, "it's a trap!"I have the amazing superpower of starting lots of personal projects but never finishing any of them!
I either get bored and give up, or a more interesting/exciting project idea comes along and the other idea gets shelved, never to be worked on again. Sometimes I wonder if I have ADD or ADHD, or something?! I’m like a flipping squirrel on caffeine… Despite the fact I haven’t drank caffeine for years because of chronic migraine!
I really aught to re-visit some of my pet projects and try to finish some of them! :/
Oh, and I have an insane propensity for procrastination!
