What is a CEO?

His description fits nicely on Steve Jobs.

Quote taken from his Golden Gate Bridge Talk (a recommended watch):

I’ve often spoken to the editorial nature of what I think my job is,
I think I’m just an editor, and I think every CEO is an editor.
I think every leader in any company is an editor.
Taking all of these ideas and editing them down to one cohesive story,
and in my case my job is to edit the team,
so we have a great team that can produce the great work
and that means bringing people on and in some cases having to let people go.
That means editing the support for the company, which means having money in the bank,
or making money, and that means editing what the vision and the communication of the company is,
so that’s internal and external,
what we’re saying internally and what we’re saying to the world – that’s my job.
And that’s what every person in this company is also doing. We have all these inputs,
we have all these places that we could go –
all these things that we could do –
but we need to present one cohesive story to the world.
