- slipping on deadlines becomes cumulative and does affect your career or business; the more work that is delayed, the most difficult it seems to be to ever catch up
- there is a fast-approaching deadline for all of us, and I don't want to look back on what may be my last decade of high productivity and realize I spent most of it on Netflix and Steam
As said by others, procrastination is often a symptom of negative visualization of a task; if you can train yourself to drop the fixation of a task being unpleasant, you can overcome most procrastination.
That has worked for me; now, when I miss deadlines, it's more due to overestimating my energy than falling victim to my own procrastination.
