Point # 2 is something I realised 2 years ago - although it is an oxymoron. We all trade for money. But actually, we need a process (entry, sizing, trailing, exit, accepting a loss in case of failure). Once we find a process (which includes your trading system) that results in high probability trades, the only objective will be achieving the process goal, money will be the by-product.
Point # 4: Explains why I have dropped the idea of becoming a full-time trade, though I miss many trades at times of peak working seasons, like this month in Nifty. The reason is, in the market, the winning or losing is not in our control. But we all need means to survive. So once the need of earning is addressed by some other means, the desire of taking trade every day and winning is gone. And same thing (the alternative means of earning) keeps you busy enough of taking care of the point 4, so that you don't watch tick by tick.
Time = Money, it better be spent on which the outcome is under better control, trading is not the right candidate.
I have listened to one webinar of Yogeshwar Sir, where he was scolding someone who was planning to quit 9 to 6. Just to make this point double proof.
