Often when I start feeling guilty for putting off a task (even if I genuinely didn’t have time), the guilt makes it harder for me to get back to it. It’s an additional emotion that I have to barge through in order to get started.

What if the person is annoyed with me for still not having replied? What if they’ve followed up with a strongly worded email that I’m now going to have to suffer through? And I’m going to have to come up with an excuse for taking so long. This would have been so much easier if I’d done it yesterday.

The guilt increases exponentially. How do you dispel it so that it’s not in the way of actually getting to the task?
