Alexander Graham Bell

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.

<b>I had made up my mind to find that for which I was searching even if it required the remainder of my life</b>. After innumerable failures I finally uncovered the principle for which I was searching, and I was astounded at its simplicity. I was still more astounded to discover the principle I had revealed not only beneficial in the construction of a mechanical hearing aid but it served as well as means of sending the sound of the voice over a wire. Another discovery which came out of my investigation was the fact that when a man gives his order to produce a definite result and stands by that order it seems to have the effect of giving him what might be termed a second sight which enables him to see right through ordinary problems. 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.

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.

Por regla general, un hombre debe muy poco a aquello con lo que ha nacido. Un hombre es lo que consigue hacer de sí mismo.

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.

Don't keep forever on the public road, going only where others have gone.

Concentrate all your thoughts upon the work in hand. The Sun's rays do not burn until brought to a focus

Ketika satu pintu tertutup maka pintu lain akan terbuka... kadang kita terlalu lama terpaku di depan pintu tertutup itu.

Geh nicht immer auf dem vorgezeichneten Weg, der nur dahin führt, wo andere bereits gegangen sind.

A man, as a general rule, owes very little to what he is born with – a man is what he makes of himself.

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.

Before anything else, preparation is the key to success.

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.
