Do you know enough people full stop?
When can one safely say one knows enough people?
Can one ever know too much of anything?
Is knowing superfluous stuff too much?
Isn't most stuff superfluous?
Don't you think that is too much information?

Don't you believe that the pen can attack from a distance?
Do you believe that distance is more important than penetration?
Is penetration the be all and end all?
