Luck is what happens when preparation meets opportunity.

No source in Seneca’s writings. The Latin and English texts held here (all 124 Letters to Lucilius and On the Shortness of Life, On Tranquillity of Mind, On Providence and On the Happy Life) were searched for ‘luck’ and ‘fortune’ together with ‘preparation’ and ‘opportunity’, without a match. The thought appears unsigned in The Youth’s Companion of 25 April 1912, p. 222 (seen here on the scan; found through Barry Popik, 2011, and the Wikiquote Talk page, 2010: ‘He is lucky who realizes that “luck” is the point where preparation meets opportunity’); Popik also finds it in bankers’ advertising of the 1920s, and in this exact wording in a 1928 newspaper advertisement; a 1970 sports column calls it ‘an old proverb’. It has been credited to Oprah Winfrey (from 1991), to the American football figure Darrell K. Royal and to the insurance salesman Elmer G. Letterman, and to Seneca from 1999 at the earliest found by Popik and Wikiquote, always without a reference. Its first author is unknown. The Talk page points to a kindred thought in On Benefits VII.1, where Seneca quotes Demetrius the Cynic on the wrestler who masters a few holds and watches for the chance to use them; it does not mention luck, and that work is not held here.

One of the most shared ‘Seneca quotes’, on business and sports posters and in self-help books; Bob Woodward’s The War Within (2008) has General David Petraeus remembering it as ‘the Roman dramatist Seneca the Younger’s adage’. No work, letter or passage is ever given.

Good fortune is mostly the reward of being ready when a chance comes.

Passed off as ancient Stoic wisdom. The saying is an American one of the early twentieth century, used by banks in their advertising and later by coaches; nothing in Seneca’s surviving works says it, and Stoic writing treats fortune as something to be indifferent to, not something to engineer.
