“Life isn't all Golf.”
Though Woods might have used this phrase, it is one dating at least to the early 20th century; the earliest published use thus far located is in "Mr. Lyncargo's Professional, by Frank Savile, in The Badminton Magazine of Sports and Pastimes (1906), p. 498, where a character declares : "Life isn't all golf. There are other duties, sometimes."

“Golf is a good walk spoiled.”
"Twain probably never uttered [these] words," according to R. Kent Rasmussen, editor of The Quotable Mark Twain (1998).
"To play golf is to spoil an otherwise enjoyable walk" is found in H.S. Scrivener, "Memories of Men and Meetings" https://books.google.com/books?id=cYgCAAAAYAAJ&q=dicta#v=snippet&q=dicta&f=false, in Arthur Wallis Myers (ed.) Lawn Tennis at Home and Abroad New York:Charles Scribner’s Sons, 1903, p. 47. Scrivener attributes the aphorism to "my good friends the Allens".
