How do I begin with my memoir about my life-changing trip to Rajasthan?

Jaipur is known as the Pink City, Jodhpur is the Blue City, Udaipur and Pushkar are the White Cities, Jaisalmer is the Golden City, and Bikaner is the Red City. I believe Jodhpur is the one that was the most attractive city to me and Desert Camp In Jaisalmer being the second spot.
