I would say, as an entrepreneur everything you do - every action you take in product development, in marketing, every conversation you have, everything you do - is an experiment. If you can conceptualize your work not as building features, not as launching campaigns, but as running experiments, you can get radically more done with less effort.

I asked all of our recruiters to give me all resumes of prospective employees with their name, gender, place of origin, and age blacked out. This simple change shocked me, because I found myself interviewing different-looking candidates - even though I was 100% convinced that I was not being biased in my resume selection process.

The attributes for entrepreneurs cut both ways. You need the ability to ignore inconvenient facts and see the world as it should be and not as it is. This inspires people to take huge leaps of faith. But this blindness to facts can be a liability, too. The characteristics that help entrepreneurs succeed can also lead to their failure.
