A key thing I have not heard is " I purchased the course, practiced what I learnt and made money from my investment."

I wonder why I have not heard that, is it that we are seeking the holy grail and attending courses attempts to fill that void that exits for most if not all traders. Also I am keen to know what specifically people learnt from a course they attended and how it helped their trading as comments received so far have been vague and lack real content about their experiences and how it has helped them in their trading. Am I alone in this?
