LIZ: If you want to get really crazy about staying motivated, set up a variable reward system for yourself. I created a habit of focusing on a single task (no checking Reddit or email!!) by pressing a random number generator button every time I successfully concentrated for an hour. If the generator (which was set to pop out a number between 0 and 10) gave me a 2, 3, 4, or 7, I allowed myself to eat a bowl of ice cream (cookie dough!) after lunch that day.
