@Bill, I can totally understand why you feel the way you do about your “success”. I often feel like an imposter when people tell me how creative I am, or some such thing. I very rarely come up with an idea from scratch – instead I borrow, adapt, and build on ideas I have seen elsewhere. I can problem solve from a question to an answer in quite creative ways at times, but I often miss the forest for the trees as well.
BTW, I love the expression on your cat’s face 
My cat is a Ragdoll. He likes to try and help me sew, by sitting on the fabric I am cutting out. At least he is too big now to sleep on top of the sewing machine like he did as a kitten!! I would have more cats if I could, but hubby is a dog person, not a cat person
