1. Listen to all of 10 hours of rain and thunder on Youtube whilst working every day. I get into a state of flow much easier listening to that than practically anything else.
2. Text important people in your life to say you're offline until lunch and then turn your phone off and put it in a drawer.
3. Get a water jug so you don't have to keep getting up to fill your glass of water.
4. Create an alternative profile in Chrome or Firefox without your usual social profiles and add a site blocker blocking social media to it.
5. Print 4 rows of 10 boxes on a piece of paper and tick a box for every hour you successfully do work without distractions and put a cross for every hour that you are distracted. If you hit 40 hours without distractions give yourself a prize.
