No worry. Print 160 exams with several multiple choice questions and forget writing the beginning of one. Then, have the brilliant idea of printing this question and glue it to the 160 exam sheets. There you have. Boredom.
Easy.
Boredom is a source of daydreaming, mind-wandering, thus, creativity.
If you make a mistake numerous times, don’t worry. Make boredom the solution by correcting your mistake as many times you need.
You will experience the opportunity to stop by doing nothing useful. At least it is what it seems, but appearances can be deceiving when you turn an obstacle into a trampoline.
