Author and investor Tim Ferriss took some time off from his 4-hour work week to give the first keynote on Day 3 of The Next Web Conference.

Saying that there are real “haters” out there, both on the web and face-to-face, Ferriss said that he at first was very concerned with any criticism of his best-selling book, but that later he learned to “contain excessive responses”.

Using the Air Force Blog Assessment tool that the US Air Force uses to determine how they will respond to negative blog posts, Ferriss says that he usually either ignores junk criticism or “pours gasoline” on blog posts that he finds are somewhat useful, but that he would like to see expanded.

On his own blog, Ferriss is ok if people attack him on his blog, but he has a zero tolerance policy for users that attack other users. He feels that he doesn’t have a responsibility to publish negativity, and often deletes comments.

After the publication of the 4-Hour Work Week, Ferriss said that all of the mainstream press that he received was overwhelming and that he was naive because he didn’t research all of the reporters that he interviewed with. He says that he now requires all interviews to be recorded on his end, which he feels gives him some added insurance against attack pieces.

“The Cross-Media Trinity: Avoid, Acknowledge & Act” is what Ferriss has termed about how he filters news media and haters. He says to avoid traffic/media manic-depressives, that acknowledgement is usually more powerful than apology, and don’t be reactive otherwise you won’t control your life.

Ferriss’ 7 Principles are:

1. It doesn’t matter how many people don’t get it, focus on the people that do
2. 10% of people will find a way to hate you – don’t take it personally
3. When you try to please everyone, you end up alienating the more valuable people
4. If 95% of the people like you, you’re not doing it right
5. You want to practice being foolish and stupid
6. Living well is the best revenge
7. Keep calm and carry on

Ferriss also took down the house by taking off a fake full-arm tattoo when he said his “practice being foolish and stupid”.

We certainly hope Tim will be back next year!
