I spend Almost all my free time making origami models. It's fun and makes me feel good. My last super complex model was The Divine Dragon Bahamut ( attachment below). You can also visit my Youtube channel for more models:

How about you? Are you interested? I think it's good to give it a try if you haven't yet. Believe me, you'll like it. I can even provide you with some hints.
Cheers
