Yes don't be a jerk. I mean why to be one? When we respect our team members they respect us too, from core of their heart. If you're a jerk, chances are your team may pretend that they respect you and your opinion and wait for them to leave your startup and see how bad mouth marketing they gonna do about you.

Great leaders are great humans. We have to be a good human before becoming a good leader.

Leaders are humans, not god. They have their weaknesses. When we want to ask for something special from the great leaders, we need to tolerate their special tempers. They can change the world because they have an unique way of thinking that we cannot understand.

Of course, being a jerk does not make you a good leader.
