Total productivity boost

I have discovered a quite simple productivity boost method:

Ignore your email. Totally.

If there is anything worth doing, people will eventually call you or find you in person.

When people ask you if you have received their mail, simply say you either never received it, or your email account is having some problem, or your were out in a meeting and his email was buried in other mails.

You will not be fired as long as you talk to people nicely.
