I might add a couple of more thing re: the psychology.....
When reading HC. One of the best way of learning is to keep an open mind to both sides of a discussion! And what I have learnt in my time on HC is invaluable.
(There are a couple of companies that I post on that I have an entry point already decided if the SP gets there, if it does not then so be it. There are also a couple that I have held previously and if I have held them previously I do not hide it. There is one that I am watching very carefully but currently there is doubt so aI hold back. Hope this helps in your attempt to understand the phycology.)
