You mention that sometimes, what we call 'laziness' is a person not valuing a task or seeing it as important. I agree! There's always the famous case of the student who doesn't try in math class because they believe they'll never "use it in real life." But why does failing to see the value of a task indicate laziness? A person not trying at something they see as unimportant is quite rational and wise. We might disagree with what they value or do not value -- and we can work to persuade them that the task is valuable -- but seeing their lack of effort is not a moral failing or an internal flaw. It's a social problem with a context we can work to address. A lot of math teachers are bad at conveying why math matters in the real world, after all. The same is true of many other goals many people feel unmotivated about.
