Do we specify a character flaw by name?

My 9 year old son tends to find the easy way out in whatever he does. For example, he has to get a math book in our math ands science pile of about 8 books. After one look he whines and say he can’t find it. When I go look for it, the math book is in the pile, but slightly covered up by a wider folder on the top. This kind of situation happens a lot and I think it’s due to laziness. So I decided to tell him, when you only look once and not choose to be diligent, by lifting up each book, you are choosing to be lazy. Is this harmful? I grew up without much emotional guidance from my mother and did not recognize the emotions I struggled with until I was in my late teens. I met a mentor then who would label the more complicated emotions she saw in me when I was interacting with people and when I explained what I thought of a person (like jealousy, pride, resentment, anger).. after a while, I would recognize patterns in myself and we would discuss the underlying problem to why I behaved such a way, how to overcome etc. After doing these with her quite a bit I began to recognize these emotions in myself and others. Would you recommend doing this in TSG?
