We are all given the same 24 hours, though like many things time is relative, every day is still a new chance to change for the better. Life is only 24 hours. No past. No future. Only here and now. Subtle improvements in the present moment stack on top of each other, like tetris bricks. Eventually those improvements compound, creating a perfect line and your score goes up, and you keep getting better each time a block (obstacle/chance for improvement) comes falling down your way.
