The idiom "on your mark" means that someone is ready or prepared to do something, and they are waiting for the signal to start. It can also mean that someone is focused or determined to achieve a goal or complete a task.
The origin of the idiom "on your mark" is not entirely clear, but it is believed to have originated from the world of sports. In traditional track and field events, runners would line up behind each other at the starting line, which was marked by a chalk line or a tape measure. They would wait for the signal to start running, which would be given by the referee or the starter. Over time, the idiom has evolved to mean something more metaphorical. It is now used to describe someone who is focused and ready to achieve a goal or complete a task. This evolution reflects the changing nature of work and the increasing importance of being prepared and focused in different fields.
