can't disagree with you. but in my opinion people became more emotional in last 10 or 15 years with intagrams, facebooks , snapchats  etc
people who are emotional and they know it, should not come to this violent market where newbies are slaughter every minute.
of course its hard to keep thinking logically  when you bank goes down 20 or more % unless youre sure and confident with  what you doing and why youre doing it.
as an example people used to see me as cold since i remember myself, regardless i was really emotional when no one was around. Somehow i learn to separate those 2 things in my life and use them as needed so even if trend goes down and i didin't planed it im not panicking
