If this is in response to an earlier discussion on HN what it is exactly that an incubator does for the entrepreneurs that sign up with them then I hope that this is not typical.
An entrepreneur that does not fear failure still has to be born I think, almost all successful people are at some level worried about not succeeding.
You transcend that fear by becoming excellent at what you do and by giving it your 100%. And if you fail, you try again, this time with more experience. Rinse, repeat until you get it right. Almost everybody fails a couple of times before they get it right, the exceptions merely confirm the rule.
And you should get a team of advisors around you, people that you can trust completely, before you start negotiating with any VC or incubator.
After all, you are emotionally involved, you may not see things too clearly and outside advisors can keep your feet on the ground. You will make a better deal that way.
The VC is on the other side of the table during the negotiations phase.
