Day 5: Memorize a Poem
Give yourself a cognitive boost—and invigorate your spirit—by committing a bit of poetry to memory. For starters:

The way of love is not
A subtle argument.

The door there
Is devastation.

Birds make great sky-circles
Of their freedom. How do they learn that?

They fall, and falling,
They're given wings.
