Twists of fortune, wedding vows, the woes of the economy, dreams of riches. You might write about what it was like being a poor college student, or what you'd do if you won the lottery. Or about what true riches are, or different kinds of poverty: poverty of the spirit, of the imagination, of the pocket. Have you ever encountered true poverty? How about ridiculous wealth? Most of us probably fall in the huge spectrum in between, but if you've had any experiences with the extremes, it might be interesting to write about that.
Happy New Year!
