I honestly don't know if that's true. Everyone I have ever known who was supposedly being "lazy" turned out to have some serious personal issues, often issues that were not being identified.

In my experience, if you want to cure "laziness," the best thing to do is identify the underlying cause of the failure to get anything done and address that.

I homeschooled two special-needs sons who had a lot of issues that did not resolve for being lectured or something. They resolved by figuring why X was happening and addressing that.

Sometimes other people find it empowering to get that point of view put out there. It's an epiphany for some people that they aren't actually lazy like everyone has always told them. They just don't have the energy for some reason and addressing that can help make their life finally work after decades of frustration.
