It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently.

Hi,
Mr. Buffett another famous quote is:

"It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently."

It let me understand that building something need time and you can destroys it easily. Why destroys something that take you so much time to build and why build it and destroys it? Don't you feel that it just wasting your time?
