Pessimistic opinions are more plausible than rosy thinking.

Pessimists just sound smarter.

But you’re not in business to sound smart, or impress people.

You’re in business to make money.

Pessimists don’t make money, because no one can make money on a worldview that everything is going down the tubes.

Only optimists can make money, because only optimists see a brighter future.

Who cares if people laugh at your optimism.

You’re not an entrepreneur in order to impress.

Leave the pessimism to the people that want to impress.
