In my early days of sales, I did quite a few things that I *thought* would work and I *thought* sounded reasonable, until a manager beat it out of me. In order to learn sales, I had to come at things with a humble, "I know nothing" approach and accept instruction as a tabula rasa. That much I think is helpful as well.
If you can emulate this in your poker game you will find that you will soon suceed.
