Yhea this is nice but this simply does not work on all websites. The edge between working and browsing the web can be very thin on some websites. For Facebook it is easy just block it completely but reddit and youtube are difficult so what I do is that I use a plugin called stayfocused it allows you to set a amount of time (for me 30 min) that you are allowed per day to be on the websites you listed. On my second browser I place no restrictions like that but use ublock origin to block everyting untill it is broken. So for example i remove the recommendations from youtube and it's search bar. On reddit I remove the list view so only a single post shows correctly. For me this works way better because the rules are fair and that makes sure you do not just remove the entries from your host file for example just a few days after you entered them.

Even better than that:

1. apps like freedom, selfcontrol.app, or coldturkey

2. regular sleep and exercise. If you find it hard to go to sleep on time, lie down in a dark room for an hour and listen to an audiobook or call your family.

3. When you start a thing, write down the goal and the "why" behind the goal.

4. Find ways to identify the incremental signs-of-success in any task. Apply the TDD mindset to other things.

5. Pomodoro technique to combine 3 and 4.

I waste time when I go to YouTube because of all the recommendations I get. I added custom css to Safari and added display: none to all those divs so now I never see recommendations and just watch the thing I'm looking for.

Lol, same for Facebook here. I don't have an account (I had one years ago), but the Internet is full of FB links. Considering doing the same for Twitter, even if I never used it (it is not so popular in Europe).

for good measure, here are 83k additional domains:

I've been using the Leechblock extension on Firefox. It lets you set browsing quotas per website. It has been good for reducing time wasting habits.

But. . .then. . .how. . .did you get to this site?
