The man looking in the mirror is often the last to know.

One soldier, Ryan, to another, Leo, who is another city. Ryan: Leo, I am cutting the yellow wire on the fuse to a 50 megaton atomic bomb. It is identical to the one you are disarming. I will be talking my way through the procedure. If my communications cease, cut the black wire. "Our Father which art in heaven ... for Thine is kingdom and the power and the glory forever." and the yellow wire was correct. Cut it.

It is seldom how many people you know that counts, networked to the hilt as it were. It is who you know that counts. Having a network of 1023 people is not only time consuming, but it is like herding butterflies. On the other hand, if you have a "go to" phone number, it is like money in the mattress. (The saying used to be, "money in the bank", but no longer.)
