First of all, its funny how you wrote the headline, What is procrastination? Then accompanied it by a photo of a tired man and lots of work on his desk.. Lol 😆

Over labouring one's self is not ideal, and avoiding excessive work is not to be mistaken for procrastination..

Other than that, you have written a well organised points on the types and how to avoid procrastination. Undoubtedly, Proper planing is a vital point in avoiding procrastination, but as we plan, we should not over think it, cause that would shift us in the perfectionist zone.

Best of luck my friend.
