[Title] "Time Management Tips"

"The day, alas, is only 24 hours long." [a timeline]

"But… have you noticed that the day is circular?" [a clock-circle]

"24 hours is its circumference. Thus, its radius is 12/π, or roughly 3.82 hrs."

"Hence, the day's area is roughly 45.8 square hours."

"DAYS AREN'T TOO SHORT. THEY JUST HAVE UNTAPPED DIMENSIONS."
