If photography is painting with light, then writing is painting with words. Write a long paragraph today–about anything–being as descriptive as possible.
Take your character on a boat ride. While you’re at it, feel the breeze on your skin, listen to the sounds of the engine and the water, and smell the briny air. Write exactly what your character experiences and the significance of each of those sensations.
Where does this staircase lead? What does your character hear as he climbs? Silence? A raucous party?
Today, take one of your favorite scents–it could be an herb or perhaps a perfume or your favorite food–and write about it not mentioning the way it smells, but through the lens of touch instead.
