One has to be kept cool at the time of frustration, otherwise he will went wrong in his track/course.
Please correct my sentence if any fault you find.
Thank you Anglika.
But, could you tell me what you mean the `go off course'?
In the dictionary, go off has lots of meaning, really it is tough to understand.
"off course" = not moving forward as expected.
A ship sets a course for a voyage; if it goes off course, it has changed direction.
It is the opposite of "on course" = going in the required direction.
