Mental health professional here (well, currently on internship). "Giant red flag" is a bit of an overstatement in this particular situation. It is very common for people without significant attention problems otherwise to have major difficulty self-motivating and structuring when working independently. Many of my depressed and anxious clients became so by getting further and further behind, because there was no structure or accountability imposed on them and they simply did not know how to do it themselves. Most of them did not meet criteria for ADHD and improved quickly with scheduling, goal-setting and accountability systems. That's not to say that procrastination is not a symptom of ADHD. It is. But the modern world is built to distract even the normal, and most people are capable of developing bad habits. Also, the actual ADHD diagnostic procedure is very involved (3-5 hours of testing that can cost upwards of 2k). A lot of diagnoses aren't actual diagnoses, and no one is qualified to make a Dx from a brief verbal assessment. So long as we keep those cautions in mind, I agree that if a person thinks they might have ADHD, by all means look into the symptoms, do a little research and consider getting tested.
