Of course. For the statistics I used all clients and did not cherry pick, but you only have my word for that. And of course there is selection bias for who gives me a testimonial.

That said, those testimonials and statistics are the best that I have to make my point.

If you want me to provide you a perfect, infallible argument to persuade you to change your life, you are going to be waiting a very long time, because I am neither interested nor possessing the time and energy to do it.

If you want evidence that has signal, then that is what I have given you. You can ignore it and/or pick it apart, and get nothing from it, as you seem to have chosen to do.

Someone else might get quite a lot of value from it, if they use the strategy of looking at signal rather than assuming that they are right until proven wrong.
