There are three tricks I've found work best to stop procrastinating.

1. Ovsiankina effect. The effect states that an interrupted task, even without incentive, values as a "quasi-need". It creates intrusive thoughts, aimed at taking up the task again. [1]

2. Structured procrastination. [2]

3. Concentrating on the steps to complete the task, not your feelings and emotions about completing it. Action vs. state orientation. [3][4]
