A fine line

So a fine line is a very thin line, used figuratively to refer to a small difference or distinction between things: There’s a fine line between testing someone and entrapping them. Sometimes there’s only a very fine line between genius and madness. Usually, one of the things is good or OK, and the other one is bad. The bad one comes last.

- There’s a very fine line between personal ambition and ruthlessness.
