This reminds me a lot of Dale Carnegie's "How to Stop Worrying and Start Living".

In the first chapter he talks about how successful people often sit once or twice a week and write down the mistakes they made in order that they might make them less in the future.

The one that stuck with me the most of course was Benjamin Franklin's "Fool Things I've Done" which he wrote into every night.

Of course the book that helped me quit smoking, Alan Carr's phenomenal (albeit, (car salesman with rust proof undercoating to sell)-esque) reminded me of Carnegie's book as well.

The moral of the story for me? I need to reread Carnegie's book! Added Meditations to my cart though. I buy almost every book I read about that sounds cool. Working my way through them one by one!

Maybe I'll start a fool things I've done as well.
