It’s important to acknowledge and reward yourself for achieving even the small tasks. It creates a sense of motivation and releases those feel-good, productive emotions that spur you on to achieve even more. Make your reward proportional to the task you completed so getting a bite-sized task done gets you a cup of your favourite coffee or snack. Then plan a weekend away or fun activity for the bigger stuff. Personally I try to make staying focused more fun by using the app Forest. It turns productivity into a game. In the game, you can plant a virtual tree at the beginning of your work time. If you maintain focus for the duration of the timer, you’ll grow a tree to add to your forest. It’s rewarding when you can eventually grow a forest.
