I'm 37M, with 3 kids (10,7,4), married. I'm getting control of my fitness, mindset and happiness in the RedPill way. My 'old' hobbies are reading, TV, and computer games, but I want to do 'better' things. I'm finding I have a fair bit of time in the evenings, after work after the kids go to bed. I do most of my working out/bike riding during the day. What hobbies can I do at night?

(I'm an engineer. I like to use my mind. I've started developing an interest in cooking (paleo))
