Have you heard about Object Writing? How to get out of a writing slump

Whenever I am in a slump and can't get myself to write, I try Object Writing. It's this sense-based creative writing task for songwriters but I think it works for anyone who writes, be it songs, stories, or articles.

Every day, on objectwriting.com you get one word and you have 10 minutes to write about it using your senses, so taste, touch, sight, sound, smell, body, and motion. Today, for instance, that word is "system".

Have any of you tried it before? What are your ways of dealing with lack of inspiration and energy? I thought this could be a space to share the pains of being a writer and find some encouragements from others!
