I'll post an observation here...
My ESTJ husband can't procrastinate, but he can be lazy.
He will work diligently through the week, concentrating on nothing but his work, but when the weekend starts, it's WEEKEND. He doesn't check e-mails from work - that's for monday. He doesn't talk about work, unless there is something really interesting or he wants my opinion about something.
I'm totally the opposite. During week, I'm anticipating the weekend. During the weekend, I'm imagining the next lessons. I procrastinate a lot, but I can't be lazy. I'm restless.
