Carl Jung said that we all wear different masks, going through life switching our persona to match some type of social normalcy. But what if we could literally wear a different mask each day to show our true feelings or to hide from the IRS or an ex or to try something new, step out of our bubble without ever having to tell anyone? What would the world be like? Would we all get along? Would shit hit the fan? At least we'd know to steer clear from the guy with the Deviant Smile mask on...Write about it. Perhaps it goes swell. A little too swell. Stepford Wives swell. Or R.L. Stine's The Haunted Mask awry.
To challenge yourself even more, wear a Different Writer mask. Don't write the way you always write. Write in Olde English or if you're from the south, write like a yank. Have fun. Go schizo. Just get writing!
