And he noticed that the more the he wrote, the better he felt. He opened to his wife, and to his work. His depression lifted.*
Susan Cain

James Pennebaker‘s personal experience of writing out
the difficult things in his life
turned into forty years of study;
Again and again he found that those who wrote out their troubles
benefitted more than the test groups who were asked to
write about mundane things.
Of course, we can write about the good things, too, including
our ideas and hopes:
It’s more likely that action will follow the words.

*Susan Cain’s Bittersweet.
