"A boo is a lot louder than a cheer. If you have 10 people cheering and one person booing, all you hear is the booing"

In this quote, Lance Armstrong is highlighting the power of negativeness and how it can overshadow positivity. He compares a "boo," which is a negative expression, to a "cheer," which is a positive expression. Armstrong recommends that even if there are ten people cheering, the someone booing will be the loudest and most noticeable. This can be interpreted as a commentary on humanity and how we tend to concentrate on the negative rather than the favorable. It also acts as a pointer to not let one unfavorable voice drown out the lots of favorable ones. In general, Armstrong's quote encourages us to be conscious of the impact of our words and to strive for positivity in our actions.
