Invest in things and items which are robust to time and money. White Tesla Model 3 (uber-base model, black interior, no options or enhanced autopilot) as robust to time.

Also iPhone SE.

Also leather HAPTIC products.

Also film Leica M cameras. Like my film LEICA MP camera, and Leica lenses (Leica 35mm f2 Summicron ASPH).

Also, Rolex watches.
