confidence in yourself and your abilities
But for girls who lack that armor of self-assurance, the insecurity I felt after reading Seventeen must have been even more unbearable.

A phrase that is utilized to express positiveness, a guarantee, or just general "knowing" of a person, subject, or event.
Jake: "Was the party at TJ's really as cool as everyone said it was?"
Dre: "Hell yeah man. Everyone was having a good time."
Jake: "Man, for real? And I missed it?!"
Dre: "Rest Assured Jake. You missed more than you'll ever know..."

Normally heard in the context of `mutually assured destruction`; when something is mutually assured, it is guaranteed to happen to both parties involved. This phrase is normally linked to discussions involving nuclear weapons, where `mutually assured destruction` means that we are all guaranteed to die.
Hindsight is always 20-20
But looking back it's still a bit fuzzy
Speak of mutually assured destruction?
Nice story...tell it to Reader's Digest!
