Time to get off your ass and actually do something in your life other than work and collect shit -
You have hundred of guns, do you ever fire them, are you able to break them down, clean them and modify them yourself? If guns are your hobby then pay someone to teach you how to become a better shot by taking classes at the range.
Cars - you enjoy driving or just saying "look at me and my status symbol" Take them to track days, learn to be a better driver? Buy a Jeep - buy parts for Jeep - learn to work on jeep, make jeep a fun rock crawler? Buy the tools and the lift and have someone teach you how. How about buying a classic car you idolized as a child and make it a restoration project?
Take some classes - learn how to scuba-dive. Learn how to kiteboard, windsurf, or surf? Paraglide? Thought about getting a private pilots license and learning to fly?
Go on a real vacation and get out of high end hotels and concierge butlers. Go on Safari in Africa, go for a trek around NZ, hit up Peru & Chile in South America? Galapagos Islands? Corsica-Sardegna-Siciliy? Go hike the Dolomites in Italy - hire a guide!
Buy an ultralight backpacking kit and get to the back country - pack rafting in Utah. Take a 2-week hiking and rafting Grand Canyon river trip.
Buying more shit is pointless unless you do something with it.
