"Before you diagnose yourself with depression or low self-esteem, first make sure that you are not, in fact, just surrounded by assholes." — thought to be Gibson's words as a result of Twitter attribution decay, despite repeated disavowals. . The source, according to Gibson, is Steven Winterburn . However, Steven Winterburn is NOT the original creator of that quote. The original quote is the creation of Twitter account holder "@debihope" . See research by quoteinvestigator .

Bevor man bei Sich eine Depression oder geringes Selbstwertgefühl diagnostiziert...
sollte man sicher gehen, dass man nicht nur von Arschlöchern umgeben ist.

Before you judge someone else, judge yourself!

You must be able to take constructive criticism and avoid having people who inflate your ego only

Make enthusiasm your daily habit. Don't let negative people determine your self-worth. Seek friends and associates whose lifestyles and words inspire you. If you have to deal with negative people, make a conscious effort not to let them infect your thinking.

Don't feel sorry for yourself. Only assholes do that.

Look at yourself before you pass judgment. Don’t make someone else clean up your mess.

Dont make assumptions about yourself.

Sceptics are asking whether they might be avoided if doctors did less to confirm unhappy employees' suspicions that they are clinically ill. Physicians love to diagnose what they can treat, but the fact that they think they can now treat depression does not mean most patients are depressed.
Even if they are, the best advice, that few doctors will offer is this: reject the diagnosis. Throw away the the pills. Take a rest and get better naturally. For most people, that approach will work just fine. And it won't leave you unemployed. Believe me, it's a lot less depressing than suing.

If you are praised by others, be skeptical of yourself.

You have to look at yourself objectively. Analyze yourself like an instrument. You have to be absolutely frank with yourself. Face your handicaps, don't try to hide them. Instead, develop something else.

Assume the worst. About everybody. But don't let this poisoned outlook affect your job performance. Let it all roll off your back. Ignore it. Be amused by what you see and suspect. Just because someone you work with is a miserable, treacherous, self-serving, capricious and corrupt asshole shouldn't prevent you from enjoying their company, working with them or finding them entertaining.
