Look at a day when you are supremely satisfied at the end. It's not a day when you lounge around doing nothing; it's when you've had everything to do, and you've done it.
-Margaret Thatcher

well this is saying that maybe if you look a the day as a very good one than you wont lounge around and be lazy you will do everything you are sappose to do and all the chores you are soppase to do.
