A good friend who has moved to Florida to enjoy photographing sandhill cranes and white pelicans sent me an article years ago, titled "Micro Biography." It talked about writing, in 100 words or less, what your life looks like to you.
What a challenge! Would you write in terms of other people, spouse, children, grandchildren? Your JOB, past or present ? Your hobbies? Your health?
And how is what you would write today different from what you would have written 10 years ago? 20 years ago?
Although 100 words doesn't sound like a lot, you can get quite a bit of substance in that short a span.
Try it! I'm going to.
