It’s a very difficult balance to figure out what to say and what not to say in a public blog. There is a temptation not to say anything personal at all, which would sort of defeat the purpose of having a blog.
I’ve been thinking a lot about the difference between the possible and the impossible. For example, for me to become Minister of Finance of the Great Chinese Economic Union or to completely change the career structure of academia or to start a Fortune-100 company. All of that is highly improbable, but it’s not impossible, given two or three decades of hard work. I’m not breaking any laws of physics or doing anything that is mathematically forbidden.
But for me to change the past, to undo the damage by the life threatening accident I had a few years going, to have a conversation that I should have had, but didn’t. That is not merely improbable, that is impossible. The past cannot be changed. The dead cannot be raised.
