Since you don’t understand this… When it comes to public persona, there is a spectrum.
Some people, like you, are entirely private. That’s their prerogative.
Some people, like elected officials and entertainers, are pretty public. That’s their prerogative.
In between are a whole lot of people who, depending on their occupation, etc., are sort of semi-public. I’m somewhere in there. If you Google me, you find this. (I didn’t put this there. I didn’t even see it till recently, and it’s out of date.)
I’m a journalist and author. I’ve been a semi-public person since the late 1980s. A humor column about my life won a national award. To date I have about 5,000 followers on Quora and Twitter.
I wrote about my childhood in my old blog.
I’ve switched gears since I wrote that, and now I’m creating a blog on religion and atheism. That’s why I had the image.
So … this is sort of what I do. You do something else, and that’s fine.
