Work on tasks when you feel physically and mentally ready

Next time you have to do a task you dread, wait some more time.
Procrastination is not entirely bad, but a naturalistic risk-based form of decision making.

Only do the task when you feel physically and mentally ready.
For this, take some time for introspection. A short meditation can help you clear your mind and feelings related to the task you postponed for so long.

Once you feel ready, sit down and work for only 5 minutes.
Set a timer if you have to, but most likely, you’ll end up finishing the task. The 5 minute-rule lowers our stress and fear of negative consequences of our procrastination. Once engaged, you are likely to feel positive and confident about the task you’ve been postponing!
