Is it already too late for most people?
Someone (I forget who) once observed that people had only until a certain age to reject their religious faith. Afterward they would have answers to all the objections, and it would be too late. That is the kind of existence you must surpass. This is a test of your strength as a rationalist, and it is very severe; but if you cannot pass it, you will be weaker than a ten-year-old.(overcomingbias.com)
I wonder how true this is. And fear that it is more true than not. And further, I fear that you can almost never see this in yourself without exahuastive (and exhausting) ongoing effort.
But you should try.
