Shouldn't waste your energy worrying about "everybody". YOU be logical and disciplined. The rest will figure it out eventually (or not).
As an aspiring trader you need to be willing and able to handle MORE losses at that stage of your trading career.
Do you think "LOGIC" is different for those who not put together months of being profitable as opposed to a seasoned trader? People who pay to do the TST or Gauntlet lack funds to have a trading account? Those that not done enough back testing and wing it, cause they say they learning what not to do because of one day of trading, I don't see the logics. Tough enough to trade, but think of having journal and keep posting all the time is wrong approach, more time in back testing and refining than posting. But I agree with you that logics is needed, but all are different.
Difficult to pin down an exact definition of logic. (Can be explained a bit differenently in various applications, such as mathematics, law or other.) As it applies to trading the markets, my thumbnail KISS explanation of it is about... "If _____, then ____". The "why" of it is the logic. One of my favorite all-time quotes is from the fictional Sherlock Holmes. When asked, "just what is it that you do, Mr. Holmes"? He replied, "I observe and deduce". (And let's not forget the gem from Yogi Berra... "You can observe a lot just by watching". ) And then there's Mr Spock... "When you have eliminated all other possibilities what remains, regardless of how seemingly improbable, must be the truth". Trading is much about that process. If you're figuring it out on your own, one probably needs to see a lot of data and spend significant time cogitating over it.... as you well know.
