The secrete handshake comes from your own brand image and active networking, though -- that is, you truly care about those few people (your supporters) and put their interest ahead of your own, make them more successful (whatever this "successful" means), and the long term relationship will benefit you in the end.
Feeling too proud of oneself may not be a healthy attitude. One should clearly understand the difference between confidence and arrogance, humility and self-humiliation, etc.
It's about who you know instead of what you know (I assume you are already at the level of leveraging who you know rather than solely relying on what you know to make a living).
Starting from scratch may not be a bad idea to reestablish this network if you don't have any within your current organization.
