What is the One Thing That Changed Everything In Your Trading? It is actually the things that changed everything in your trading. I am posing it that way so that you select only the best things, with a focus on the one thing that led to the "HaHa moment". The one thing could be an insight, an observation, an idea, a thought, a book, a thread, a blog, a mentor, luck, etc. It is "the one thing that changed everything" in your trading world. I was chatting to a friennd who is new to trading (newbie who wants to have fun in trading with the intent to maybe take it more seriously if it makes money). I got a sense that my friend views trading as only/mainly buying and selling transactions, but what I want the friend to FIRST see is that the task of a trader is to locate upsides that are worth on average more than the downside, and to earn the different as a result of his labor/insight/risk taking. If this sounds trivial to you, I am not convinced my friend sees it yet. The day when my friend sees , I am thinking I will get a question such as "this is gambling", or a more profound one, "why would anyone sells to me an upside that is worth more than the downside on average, as this would be in contradiction with markets which should price this out". When that day comes, I will share with you what my answer would be, but you can tell me what I should answer my friend, and also what you think are the one things that will change my friend's view on trading. Please make them as items in a priority list. I did not want to tell my friend all the other steps, otherwise my friend may give up. What do you think?
