I think that, instead of saying "you're not lazy", we should take the stigma away from laziness and say "you are lazy, but don't feel bad". Laziness is a character trait present in all humans, some more than others, and we should acknowledge it and work to become less lazy, without punishing it or being ashamed of it.
You are "lazy" if you don't do something that would benefit you because it's too much effort. That sounds reasonable, right? Except according to this article, you're not lazy, you have "internal resistance." Or in similar articles, you're not lazy if you have depression or ADHD, because it's your mental illness.
But then, who is lazy? Where do we draw the line when someone is depressed vs. merely sad, or ADHD vs. merely inattentive? Moreover, since you can't always tell of someone has a mental illness and you definitely can't see "internal resistance", you technically can't state that anyone is lazy.
Now, I don't want to attack people with mental illnesses. If you have depression or ADHD or burnout or are overwhelmed, you're not a bad person. But you are lazy. Calling it something else is just beating around the bush.
Instead, we as a society need to change how we look at laziness. Just because you're lazy, doesn't mean you should punish yourself, or consider yourself "worse" than someone with more discipline. Don't even try to just "power through" the laziness. None of those things work, and often actually lead to more laziness. Honestly, the author does a good job explaining what you should do. But - if you're lazy, you're lazy, and calling it something else like "internal resistance" is just sugar-coating it.
