It's not the tools that you have faith in - tools are just tools. They work or they don't work. It's people you have faith in or not. Yeah sure I'm still optimistic I mean I get pessimistic sometimes but not for long.
I'm totally into new age and self-help books. I used to work in a bookstore and that's the section they gave me and I got way into it. I just loved the power of positive thinking letting yourself go.
