Alexander Graham Bell

"Mr. Watson — Come here — I want to see you.[First intelligible words spoken over the telephone]"

"Before anything else, preparation is the key to success."

"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."

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