Never tell anyone what you're going to do till you've done it.
About this quote
Attributed to Vanderbilt in biographical collections. Like his injunction to keep plans secret, this saying reflects the secrecy-as-strategy philosophy Vanderbilt applied throughout his career. He was frequently reported to have completed major transactions — acquiring controlling stakes in railroads, for instance — before competitors realized what was happening.
