Limitations on yourself often force you to become more creative. Pick 10 things that you cannot/must do in your story. Your story must be about someone of the opposite gender.
One of your 10 things must restrict or deny the use of a letter.
Another must be a word you can’t use. Pick a word you find yourself using often in stories.
Be creative with your limitations. Don’t end your sentences with a consonant. Each sentence must have an even amount of words. No dogs. Use an umbrella in the story at least once.
Make them hard but doable. Don’t give up.
