I have a habit.
I write 100 words every morning. That sets me up for the day.
You can’t plan, think or analyze within 100 words. It’s just the right length to express a single idea. There’s no room to show off, or for ego to intrude. In that sense, it’s like a haiku (but not a 140-character tweet).
I write on the topic of learning languages. That’s what I like to do, and help others with too.
Doing this, I suspect that I stimulate my right-brain thinking—a better habit than most, surely!
