" To Scottie June 12, 1940 p.451

...don't take the things in which you can get 'A', for you can learn them yourself. Try something hard and new, and try it hard, and take what marks you get...No Achilles' heel ever toughened by itself...what little I've accomplished has been by the most laborious and uphill work, and I wish now I'd never relaxed or looked back - but said at the end of The Great Gatsby: 'I've found my line - from now on this comes first. This is my immediate duty- without this I am nothing'... "
