Life is so complicated a game that the devices of skill are liable to be defeated at every turn by air-blown chances, incalculable as the descent of thistle-down.

It's funny, but... you're sort of a moving target for fortune, and you never know when it will befall you.
The two grand tyrants of the Earth, Time and Chance.
