I am in a situation where I want to learn everything I possibly could. But my greed leads me nowhere as I am constantly switching subjects. Sometimes, deciding what to learn kills most of my time.
For me, I found surfing at the age of 26. It's a crazy hard sport to pick up at a late age, but I sort of fell in love. Surfing replaced meditation, journaling, and other forms of exercise, and it gave me even more than any of those things could. It produced a level of zen and fulfillment that only two or three other activities do. I only figured that out by exploring like a mad man in my twenties, and I got lucky to stumble upon surfing.
It's the people who are too afraid to look and who get stuck in a comfortable path who don't ever figure out the real joys of their life.
Thank you for your perspective.
Instead pursuing that, find a job/work that makes you happy. You'll get more happiness "under the curve" than say, retiring early. Avoid any sort of "I'll suffer for years so I can be happy at some time in the future."
I only have 2-3 years left to live and I have very few regrets. I've always taken a moment to stop and smelled the flowers. (The smelling thing may be because I think I might been a golden retriever in my last life.)
