When interviewed by Success Magazine in 1898 Thomas Edison was asked, “What”s the first requisite for success?” And Edison answered this way: “The ability to apply your physical and mental energies to one problem incessantly without growing weary. You do something all day long, don”t you? Everyone does. If you get up at 7 A.M. and go to bed at 11 P.M., you have put in 16 good hours, and it is certain with most men that they have been doing something all the time. The only trouble is that they do it about a great many things and I do it about one. If they took the time in question and applied it in one direction, to one object they would succeed.
