Hi @Hitaru. Thanks for the great response. This sure is a nice way to organize the types of activities, indeed each of them is necessary. I have already taken a look at Cam's habit list, while they were nice activities to fill free time, nothing really seemed like an efficient alternative of gaming itself...
I would really love to know what you guys are personally doing instead of gaming. I myself am considering watching a series, youtube, reading, cooking, chess, puzzles. But I haven't tried anything yet...
