According to the text, an individual who sees time as a precious commodity, and feels guilty if it is wasted, is a “nose to the grindstone” type

I believe that statement is false

nose to the grindstone type is the type of people who are constantly working hard without providing enough time for their own self actualization. They generally do not think that providing enough time to relax and having fun is important, and tend to seek materialistic satisfaction.,

we need an attachment to see what you are talking about.
