When one door closes another door opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.

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.

The most successful men in the end are those whose success is the result of steady accretion.

Before anything else, preparation is the key to success.

I have discovered that my interest in my dear pupil, Mabel, has ripened into a far deeper feeling than that of mere friendship. In fact, I know that I have learned to love her very sincerely.

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.

My knowledge of electrical subjects was not acquired in a methodical manner but was picked up from such books as I could get hold of and from such experiments as I could make with my own hands.

What this power is I cannot say all I know is that it exists and it becomes available only when a man is in that state of mind in which he knows exactly what he wants and is fully determined not to quit until he finds it.

Don't keep forever on the public road,going only where others have gone, and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods. 'Every time you do so you will be certain to find something that you have never seen before. Of course it will be a little thing, but do not ignore it. Follow it up, explore all around it; one discovery will lead to another, and before you know it you will have something worth thinking about to occupy your mind. All really big discoveries are the results of thought.
