It's as simple as that, isn't it? If it needs to be done, then damnit, "Git 'er Done"!
It would be safe to say that if one procrastinates, then it does have a lingering effect on your mindset. At the lower end of the scale, I would even surmise that it could disrupt one's life. Something as small as organizing one's closet or cleaning out the pantry. .do not hesitate.
