I am saving this advice. It is very difficult to get people to pay for your picking your brain. I don’t even respond to such request these days. People always want something for nothing. You don’t ask the plumber or an attorney to pick their brains for free. And if you do you get a service call charge offer, stat!
I used to feel bad about not giving away what I know. But eventually, I found I was giving away info that could have been sold. I stopped and I feel much better. It’s human nature to want to help out others, it’s not to want something for nothing. Thanks for the pep talk!
