Tempt not a desperate man

When faced with a sea of troubles, take action, and in so doing end it.

Cry "havoc!" and let loose the dogs of war, That this foul deed shall smell above the earth With carrion men, groaning for burial.

My crown is in my heart, not on my head.

Murder most foul, as in the best it it; But this most foul, strange, and unnatural.

Man, proud man, Drest in a little brief authority, Most ignorant of what he's most assured.

Fear and niceness, the handmaids of all women, or more truly, woman its pretty self.
