Additional Information: This quote from Derek Sivers means that it has been proven that we are less likely to achieve our goals if we tell people about them. In the TEDTalk this quote was taken from, Sivers presents the evidence for this phenomenon and explains the reasoning behind it: essentially, when you tell someone your goal, you receive a rewarding sense of satisfaction, as if you have already accomplished your goal. Since you have already received the mental satisfaction of achieving the goal, you are less motivated to actually make it a reality.
