One changes from day to day, and... after a few years have passed one has completely altered.

My day-to-day life changes; I don't have any standard day.

But it was better to know of it than to see it in its daily monotony.

Never lament what gone wrong yesterday, gone is gone, but with a lesson of something good for tomorrow.

The great day of the Fire-eater - or, should I say, the day of the great Fire-eater - has passed.

That's the reason they're called lessons, because they lesson from day to day.
