I want to describle the following fact in a vived, figurative way. Is there any English saying about this? Or could you share some expressions or inspirations with me?
Some people are content with having a good tool while some others are not. They always want to see the inner structure, to be clear about the operating mechanism and to think about a way to improve it.
Thank you in advance. ^_^
I am not a teacher but thank you for asking for inspirations.
If someone wants to have a complete understanding of something, she may be said to want to understand the "nuts and bolts" of the subject.
Another idea: In some situations the following might be seen as a negative, if the person described is getting "bogged down" in trivial details. But, to really understand and do the necessary hard work required, someone may need to get "down in the weeds."
Those are just some thoughts inspired by your question.
