Trust me. You aren't alone. And there is nothing to feel bad about it. I have it to some degree (although a bit unidimensional - I just want to finish all my purchased math & engineering books). That brought me to the conversation with others in the first place. Keep the curiosity alive. Its a powerful, motivating force. Just don't get too anxious.

One way I think about it, is that someone will pick up the torch - someone who follows my work, blog, maybe my children. I did that for my father's dreams. If not, you are long dead already & it won't matter. That gives a sense of closure
