Carl Jung asks:
What did you do as a child that made the hours pass like minutes? Herein lies the key to your earthly pursuits.
I suppose for me it was building structures with a wooden geometric puzzle set when I was a toddler. I then discovered Legos at 6 years old, which spurred my imagination to build skyscrapers and then entire cities in my room. My dad, a lawyer, was building new rooms for a growing family, and so I was exposed to piles of masonry sand late in my childhood. I spent countless evenings building damns and digging interconnected tunnels. My confidence continued to grow and so in my pre-pubescent years I built scale models of the World Trade Center, the Empire State Building and the Statue of Liberty. Then high school happened. And then college and then life.
If I retire early, or my current job/profession gets automated, I would certainly pursue an occupation honing my craft in building architectural models with all sorts of materials and intricacies that a 3D printer would not deliver. My dream job would involve spending countless of hours building neo-classical palaces at a place like Radii Inc. The models would be so intricately detailed with all sorts of cutaways, lighting schemes, and interactive elements. Something like the railroad tracks with the moving trains embedded to the actual rooms of the New-York Historical Society.
My earthly pursuits certainly involve world-building. Creating theatrics. Making things happen. Building things.
