Dr. Singh, Thank you for this fine article! I especially like the following closing words:
So, remember your daydreaming is not procrastination, in fact it is planning to work on what you want to write. Your mind does not sleep even when you are asleep. Deep thinking goes on as your mind is awake and it makes many patterns.
Ideas come to us all the time, and this down time can also be "productive." Best wishes always, Amy
