I try to look after the little ills, with the idea that if I take care of the little ills the big ones will not come.

When I find myself unable to sleep well, I know that something is wrong.

If I find any part of my system the least weak, and not performing its duty, I consult a good physician.

The ability to sleep well, at any time and in any place, I find of great advantage.

I have so trained myself that I can lie down for a nap of fifteen or twenty minutes, and get up refreshed in body and mind.
I have said that I make it a rule to finish up each day's work before leaving it.
