Don't keep forever on the public road, going only where others have gone. Leave the beaten track occasionally and dive into the woods. You will be certain to find something you have never seen before. Of course it will be a little thing, but do not ignore it. One discovery will lead to another, and before you know it, you will have something worth thinking about to occupy your mind, and really big discoveries are the result of thought.

Man is the result of slow growth; that is why he occupies the position he does in animal life. What does a pup amount to that has gained its growth in a few days or weeks, beside a man who only attains it in as many years.

Leave the beaten track behind occasionally and dive into the woods. Every time you do you will be certain to find something you have never seen before.

Great discoveries and improvements invariably involve the cooperation of many minds. I may be given credit for having blazed the trail, but when I look at the subsequent developments I feel the credit is due to others rather than to myself.

Neither the Army nor the Navy is of any protection, or very little protection, against aerial raids.

Wherever you may find the inventor, you may give him wealth or you may take from him all that he has; and he will go on inventing. He can no more help inventing that he can help thinking or breathing.
