It's challenging, obviously, but also forces you to employ very unusual and unique language.
Inside that, I also try to not use more than 300 words without a new sub-heading, avoid too much passive voice, don't use too many overly long sentences, and don't use the same first word for more than two sentences in a row.
It's a very intriguing topic.
I just love E-Prime. I once, for a month, used social media where I would try to only use e-prime. I experienced a lot of difficulty, but I enjoyed the experience. For a week, I tried only speaking in e-prime and had to use a notepad to formulate my thoughts before speaking. I had more problems then, but also more fun explaining to people why.
Do you have any good resources on how to get started?
