Real Artists Ship - Seth Godin

Delivering unique creativity is hardest of all, because not only do you have to have insight, but you also need to be passionate enough to risk the rejection that delivering a solution can bring. You must ship.

I define anxiety as experiencing failure in advance…and if you have anxiety about initiating a project, then of course you will associate risk with failure.

If your organization requires success before commitment, it will never have either. Part of leadership (a big part of it, actually) is the ability to stick with the dream for a long time. Long enough that the critics realize that you're going to get there one way or another...so they follow.
