linking ambition to quotations in Macbeth extension
If you want three more quotes to remember under the theme of "ambition" we can extend the story. First we must create a single rememberable image for each of the next three quotations:
Quotation 4
"The very firstlings of my heart shall be the firstlings of my hand." Macbeth is no longer just ambitious - he's ruthless and unthinking in his pursuit of power.
This quotation can be remembered with the single picture of the linguine in the shape of a heart.

Quotation 5
"Upon my head they placed a fruitless crown and put a barren sceptre in my gripe." Macbeth isn't satisfied with being king - he wants a lasting legacy and feels cheated.
This quotation can be remembered with the single picture of putting on their "head a crown."

Quotation 6
"O, full of scorpions is my mind, dear wife." Macbeth's ambition has made him ruthless. He won't stop killing to secure power.
This quotation can be remembered with the single picture of a scorpion.

Now continue to link all the above images to quotation 3 on the theme of "ambition."
In quotation 3 Lady Macbeth beckons over spirits.

Link this last image "linguine in the shape of a heart" to "upon my head" to a "scorpion."
Imagine all of the above, Lady Macbeth and the spirits that she asked to come over on the star; sit down and eat her first linguine she made for each of them.

They each put the half eaten linguine upon their heads, kind of like a fruitless crown.

And then a scorpion comes along and starts eating the linguine crown that's on Lady Macbeth's head.

These images might be a little crazy but they are memorable mnemonics that will help you to recall another three quotations linked to ambition.
