I think we all like to think that, but it’s worked well for me in the past, when I had a school paper or something with a nasty deadline. I used Freedom (https://macfreedom.com https://macfreedom.com) for that. EDIT: However, these things work less and less, the more computers we own; where we used to have just a laptop and maybe a desktop, we now have smartphones and tablets - with push notifications - so unless you have a full Apple set-up with global blocking, it's decreasingly effective. And managing a blacklist router-side is a chore.
