Progress always involves risk. You can’t steal second base and keep one foot on first base.
Robert Quillen (1887-1948) American journalist and humorist
“Editorial Epigrams,” The Evening Repository (Canton, OH) (27 Mar 1924)
Also noted by him in the column "Corks and Curls," Herald-Journal (Spartanburg, SC) (11 Aug 1927): "Every big venture involves some risks. You can’t steal second and keep one foot on first."
This quotation is frequently attributed to Frederick B. Wilcox, who was the editor of A Little Book of Aphorisms (1947) where this was included, uncited.
