Not OP but I don’t feel this way at all.
My oldest son is starting college next year. That alone has been a learning experience! I coach his robotics team, that has been tremendously new experiences.
I’ve gotten three cloud certifications in the past year. I have a huge list of things I want to learn about - assembly language on Linux, FPGAs and about 20 other things.
I could spend 10,000 lifetimes and not scratch the surface of what this world has to offer.
