My father never liked to leave work half done, he would say "you do not know what tomorrow will bring", these words I kept in my mind till today. I have realized that he was right all along because tomorrow is not promised to anyone. So If you have a chance to prepare for the future, start now, finish the preparation today so that when you tomorrow comes YOU ARE FULLY CHARGED, PREPARED & READY.
The English would say "hope for the best and prepare for the worst" and "come what may". If you are fully charged or you have no outstanding work behind you will be prepared for the worst and you can handle whatever tomorrow brings.
I wish you a productive week ahead.
