Read the story. Marie and Plerre Curie were both winners of the Nobel Prize in physics. This prize is one of the highest any scientist can receive. Their
daughter, Irene, also received a Nobel Prize in chemistry. The Curies were a remarkable family. Pierre Curie was already a famous scientist when he
met Marle, who had fled from Poland. Together they discovered polonium and radium, two elements that are important in modern Industry, Pierre
Curie was killed in an accident, but Marle carried on scientific research until she died in 1934

Can you summarize this? it takes time and caution to perfect anything which must be concealed. it takes time to crush men who are pursuing legitimate trade. but one of mr. rockefeller’s most impressive characteristics is patience. there never was a more patient man, or one who could dare more while he waited. the folly of hurrying, the folly of discouragement, for one who would succeed, went hand in hand. everything must be ready before he acted, but while you wait you must prepare, must think, work. "you must put in, if you would take out." his instinct for the money opportunity in things was amazing, his perception of the value of seizing this or that particular invention, plant, market, was unerring.
