Like the saying goes, "Try and try until you succeed," but it’s understandable why one sometimes gives up because of another saying, "There’s a fine line between never giving up and being a fool." This implies that knowing when to quit is also a strength and doesn’t necessarily mean losing. However, this depends on the context. You can’t say that you know what the best choice is for others. I simply agree with the idea presented here that the person in the situation must realize it for themselves, and your role is simply to guide them.
