>>1559I think it's a really good idea, OP, but IMHO you should try to stay away from chans, news sites and (if you have some) social network too.
The interesting thing for me is the idea to avoid everything that is volatile and gives you something new every two seconds. Youtube, imageboards, TV series, reddit and social medias can be an example, cause with those at your disposal everytime you are bored you'll probably open one of them and it really kills your thinking time. Movies or longforms, on the other hand, can be ok, because they force you to mantain your attention on a single thing for a big amount of time and to reflect about it (as long you're not watching "Transformers" or reading "The 100 best meems of our recent history xD uwu").
And if you are part of that superior kind of people who like to type random things in search engines and lose theirselves in the beautiful ocean of the Wired, well, dunno if you should let this happen or no. Sure it is more interesting than random youtube browsing and sure you can find really unique stuff, but i think it is still part of those "volatile" entertaiment methods that you're trying to avoid, so for this last point think carefully by yourself what you want to do about it.
I hope you succed to reach your goal, lain.
Good fortune!
