Before digging into your duties, give yourself a warm-up routing. Go outside and do a quick, daily task like taking a short walk or picking up a latte form the local coffee shop -- then head back home and get going.
According to Science Daily studies, taking brief mental breaks actually help you stay focused on your task better. Walk away from your work for ten minutes every few hours with personalised Post-it® Note reminders.
Keep a daily record of your productivity by jotting down what you did (or didn't do) on a Post-it® Note. Be purposeful with your colours (green = "done", pink = "to do", etc.)
