From this article on Obama:
Along the way, some unofficial rules have emerged between the candidate and his aide. From Mr. Obama: “One cardinal rule of the road is, we don’t watch CNN, the news or MSNBC. We don’t watch any talking heads or any politics. We watch ‘SportsCenter’ and argue about that.”
I find that many top performers consciously avoid listening to their critics. It keeps them in state. There is just too much negativity out there.
I used to read interviews of successful people (politicians, writers, actors, businessmen, etc) saying they never or rarely listened to critics, and I wouldn’t believe it.
I was always like “Yeah, right..Come on!”.
Now I do believe it, and I understand where they are coming from.

You see, actually producing stuff and putting it out there got me to realise how negative and bitchy the general public is – most people just don’t understand and/or have no consideration whatsoever for the hard work you put in. They will just pause for a second and blurt out the first negative thing they can think of, even if they know nothing of the subject matter. And they will go on and on, as more reasons to criticize pop up in their head.
The truth is that the very first, automatic natural reaction for 95% of the population is to look for the negatives.
Unbeknownst to them of course, that’s the primary reason why they miss so many opportunities they can’t even see, and the main reason why they are unlikely to ever really be successful.
I don’t blame them, mind you – I used to react negatively all the time, too. Working on my mindset and taking action has done wonders to change the way I react. These days, no matter how awful the effort, I try to give props to anyone who actually does anything, to anyone who puts himself out there.
And I’ve learned to ignore the critics.
You’ve just got to focus on doing your best. That’s the only thing you can control.
