%% Personality study was real helpful to me.; very much so. My favorites were + are Flo Littauer books; It takes So Little to Be Above , Personality Plus....... Frankly i discovered them in my late 20s in late 20s wish it had been@ 10 or 12 years. Even though personality is a blend, she came up with some amazing accurate nicknames; watcher, worker, talker, thinker. Watcher+ thinker are introverts, other 2 =extraverts. By the way ''talker'' types tend to be happy easy+ have good work habits many times+ not so dumb . But a volume talker\LOL, loves to talk, is not going to be anywhere near as accurate as a ''thinker'' type
I go thru phases where I like to talk but the theories I work on are so advanced very very few people even have any inkling of an idea so i dont bother unless i walk into a store and someone asks me what I need and im like "wheres the catfood?"
I've always felt like that was a key part of developing a solid trading performance structure. For me, it was never about getting angry something didn't go my way - I was almost happy when it didn't because it gave me the opportunity to fix the issue by changing some aspect of the structure, ratio, product, timing...whatever.
