Alexander Graham Bell
Night is a more quiet time to work. It aids thought.
All really big discoveries are the results of thought.
Man is an animal which, alone among the animals, refuses to be satisfied by the fulfilment of animal desires.
What this power is, I cannot say. All I know is that it exists…and it becomes available only when you are in that state of mind in which you know EXACTLY what you want…and are fully determined not to quit until you get it.
You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day, no matter how much study is put upon them.
The most successful men in the end are those whose success is the result of steady accretion.
The nation that secures control of the air will ultimately control the world.
A man, as a general rule, owes very little to what he is born with – a man is what he makes of himself.
Before anything else, preparation is the key to success.
When one door closes, another opens; but we often look so long and so regretfully upon the closed door that we do not see the one that has opened for us. —-Alexander Graham Bell
