Good question. Through the years, I have become more restrictive about what I write especially with respect to others. I am aware of the fact that I am more open to share about my personal life than many people around me. Maybe it is related to fact that I want to have some, hopefully positive, effect on the world. (Maybe one day in the future it might become material for some historic research.)

There is also a lot, I do not share. I keep a personal diary and since 2010, I am recording my daily activities in Moleskin daily planners (the only planners I have found that have the same space for Saturdays and Sundays as for working days).
