As a magician, I think everything is possible. And I think if something is done by one person it can be done by others.

It means that his career requires him to be very optimistic and believe in all possibilities. If someone has done something before, Blaine believes he can do it, too. Specifically, Blaine is talking about how he decided he could perform a feat in which he held his breath for 17 minutes. Blaine came up with the idea for this stunt after he heard about a boy who survived after being trapped under a river not breathing for 45 minutes.
