"A few people I talked to in life, have this love for learning everything to the point they feel "afraid to die" before mastering something."

Damn, that describes me pretty much. Though I just feel sad that I'll die because I can't learn everything that I'm curious about. I felt this much stronger in college. Now not so much. Just trying to survive now.

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

That's very insightful.

"Keep the curiosity alive. Its a powerful, motivating force. Just don't get too anxious."

You're so right about that. I just realized I had much more zest for life when I was more curious. I should try to cultivate more curiosity.
