Web developer and designer devolute.net Sharing an office with telesales, office dogs or singing project managers can be damaging to productivity. As a freelancer I was able to escape but there’s still the Wikipedia rabbit hole. My solution has been SelfControl ( selfcontrolapp.com) for macOS. Enter your particular vices (or rather their URLs) into the blacklist and this app blocks them for however long you wish. I put in 45 minutes but usually find two hours later that I’m still focused and productive… if my phone is charging in the next room, of course.
