I am always recommending to people that they ought to journal. Keep a diary, write your memoirs, it doesn’t really precisely matter what the form is. Keep a vlog if that’s what you prefer. Julia Cameron’s Morning Pages works perfectly: 3 pages, in the morning, for your eyes only, about anything, done by hand.
A word to the wise is sufficient. Henry David Thoreau asked Emerson “Do you keep a journal?”
