Jobs also had Pixar, which had an undeniable impact in it's field.

Here's a question to test if you really believe the argument you seem to be making:

You have the idea of your lifetime. It's a billion dollar idea. You are looking for a co-founder, and find two amazing prospects.

They are equal in every way (education, drive, interests, etc) except one: Jim spent the past five years working at a startup that he just sold for $20m. Tim spent the past five years working in an office job.

You can only pick one of them. Do you prefer Tim or Jim?
