I'm relatively convinced that if I want to achieve my goals, especially as a solo founder working from my apartment, I'm going to _have_ to make an extraordinary effort to curb this, since the default is to just consume all evening (and for a work from home person like me, all day). I also have recently wondered if I've brewed the perfect cocktail of procrastination for myself as I may have some non-hyperactive ADD combined with this low accountability environment.
So, all of the normal procrastination advice applies, but I found it useful to make it harder to access these sources of infinite novelty. Especially while working, but even during the evening. There are a number of blocking apps, but most of them can be trivially defeated by a developer with admin access.
The two that I've found to work the best for me are http://getcoldturkey.com for Windows 10 and https://play.google.com/store/apps/details?id=cz.mobilesoft.... for Android.
I see no real reason to ever need to waste time on my phone. I've blocked apps like Chrome and the Youtube app permanently, and it's impossible to get around without wiping my phone (which I'm probably too lazy to do). I had to go ahead and install the Reddit app and mobile Firefox when I discovered I could install apps remotely through the Play Store on my laptop (ha!). I also block the Play Store app on the phone.
This makes my phone a phone, text messager, podcast player, audiobook player, and maps device rather than a source of infinite novelty.
For my laptop it's a little harder since I can't block the browser and and still do web dev, but the Cold Turkey app is the best app I've found to be as undefeatable as possible while still filtering specific sites. You can set up schedules, so I block sites after a certain time at night. Since, a key part of the procrastination cycle is staying up too late and then getting up later or tired, getting a bad start to the day, etc etc as the article suggests.
Cold Turkey can unfortunately be defeated if you are realllllly clever, but it makes a very strong effort to disallow itself from being uninstalled. It's a desktop application, not a browser plugin, so it can actually prevent the whole "I'll just use IE to browse Reddit" problem that Chrome plugin blockers have. And having admin privileges, it can actually enforce blocks.
This may be a bit extreme, but modern life isn't really "normal" in any possible way for our meat sack bodies and brains.
