Half the misery in the world comes first from not looking, and then from not thinking.

And I do not want you to be miserable.
But shall I be miserable if I do not find out such little things as this.
You will be miserable if you do not learn to understand little things: because then you will not be able to understand great things when you meet them.

Children who are not trained to use their eyes and their common sense grow up the more miserable the cleverer they are.
Why?
Because they grow up what men call dreamers, and bigots, and fanatics, causing misery to themselves and to all who deal with them.

So I say again, think.
Well, I suppose men must have altered the soil inside the bank.
Well done.

But why do you think so?
Because, of course, some one made the bank; and the brown soil only goes up to it.
Well, that is something like common sense.
