"Beyond that - changing environment can bring you out of a funk, bringing a laptop to a cafe with no internet can be a great option if you can do some work offline."
Even the best entrepreneurs have a really hard time focusing because they have so many different kinds of tasks that they can never really get into a flow state. Trying to do work as an entrepreneur while having access to the Internet is like trying to study for finals in a crack house.
You are right, internet is a huge time sink. On the opposite site sometimes I need to look for something and if in that moment I do not have a connection, I use it as an excuse to stop working and procrastinate.
Yeah, your defiantly going to need a lot of resources handy to work off-line and even then you probably hit something that you need to lookup online.
I can see that given the right task though it would be beneficial, the slightly slower working pace by lack of resources could be made up by the concentration you get.
It works for me studying for exams when I can have all the course content in front of me, even then though I end up finding something interesting that I want to look up in lecture notes or something that makes no sense so I need to search for a better explanation online.
