Secrets still exist
Contrary to what the world would have you believe, there is nothing new under the sun. You would have noticed the excitement that comes from new discoveries and new boundaries being broken down on a daily basis by people of all races from all over the world.
The secrets to which one man is exposed are what distinguishes him from the others. This does not necessarily imply something dark and deep, but rather something that is not obvious to others. Or reasons that most people will not want to take a chance on.
These are the things you should seek. Peter Thiel has consistently and persistently stated that monopolies continue to distinguish great ventures. A well-differentiated product will always outperform a group of undifferentiated competitors.
Strive to notice things that others do not. Take a risk and do difficult things.
