At some point, I think that most slaves/submissives are encouraged to keep a journal. Sometimes it is required by their Owner, who may read it from time to time. Others do it to process their journey; perhaps even as a way to document the changes their lives are undergoing. But, do you ever wonder why they work?
I am a fan of David Allen and his Getting Things Done method. In it, he recommends writing down everything that you have to do, in order to get it out of your mind. Otherwise, these tasks burden your mind, weigh you down, make you dread things. The key it to make your “list” and process them regularly.
I think journaling does the same thing. It allows the slave to get the things out of her mind that bother her. Allows her to process her thoughts, make them concrete by writing things down. It also helps her (or him) remember things down that may be forgotten. I know one slave who keeps 2 journals; a normal one and a bad one where all the bad thoughts go.
Anyway you do it, I encourage you to maintain a journal. Sometimes taking pen in hand and slowing down long enough to write an entry is just the right way to finish up the day.
