Have your work cut out.
[Idiom] HAVE YOUR WORK CUT OUT. - Navigating Through Tough Assignments
have a difficult task ahead.
When someone says you 'Have your work cut out,' they mean you're facing a tough, challenging task that will require a lot of effort and determination. This idiom traces back to the tailor's floor, where fabric was 'cut out' into pieces to be assembled into a garment. Just like a tailor who has all pieces cut out knows there's still much meticulous sewing to do, having your work cut out implies that the roadmap is laid out, but the journey is still daunting. For instance, if a student has to prepare for multiple exams in a week, they certainly have their work cut out for them.
