Simply put, this is wrong. There are not three kinds of laziness. Better, it's wrong to assume that your laziness and inability to act is one of those three types mentioned.
As someone who was recently diagnosed with ADHD and OCD, I can assure you, reflecting doesn't solve anything. Nor are the three types mentioned accurate. Maybe the intent wasn't to classify ADHD and OCD as laziness, but until I was diagnosed, that's what I called it.
So no. This is dangerously wrong. If you have any thought that you might have ADHD or OCD, get it checked out. It can make a world of difference, not only in medication (which doesn't have to be addicting) but in therapy. The difference just over the last month has been staggering. It's a big difference, and hard to quantify.
If you have a problem, seek professional help in understanding it. Ignore meaningless platitudes "to reflect on death" and how there are "three kinds of laziness."
