i think it would be a good experience for people to keep a very personal journal/diary that they can and DO write ANYTHING in - but then after having written in it for some time, force themself to share it with people they care about.
i think it is good to break down walls and barriers between people. i believe in being very open and straightforward.
but i have never actually kept a journal, so i don't have any real experience with this.
i don't believe in secrets. however i do always keep secrets that i am told, haha. because people are more important to me.
