I wrote 1,000 words every day for 365 days in a row

"Not quite. I didn’t actually write 1,000 words every single day. My system was a bit more relaxed."

This is a good idea.

I recommend using https://750words.com/

It has neat features like annoying you to achieve 750 words in one day, graphs showing most common words and does some basic NLP/sentiment analysis (aka you were happy/sad today).

"always creating content" is a my (relatively new) philosophy.

Even if I'm the only audience (notes/outlines/journal/etc).

Trying to spend less time writing comments on HN. Such as right now.
