That's basically like burning your money. I used to do that, long ago, when I was on Keen..I used to go back and say this didn't come to pass, how come, or why is he acting this way when you said he would do otherwise...etc.
That's when they would either push timeframes out and say he was scared or some other nonsense.
Now, I just go back to the ones who were right for me the majority of the time, and that list is super short lol.
