Let me congratulate you - you have made it to the end of the workweek! Good job! You kicked a$$!
By now, you are probably oh so over the week, so have a glass of *insert favorite (alcoholic) beverage here*, sit back, think of the good 'ol times while you await the weekend.
"By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest." - Confucius
The worst is behind you (Monday) and the best is yet to come (Friday), so enjoy today like there is no tomorrow.
