I note that he busted his trading account twice when he started out, then just kept coming back. Obviously he learned his lessons well.
I note he mentions beer and trading in this interview.. and how richard dennis once said he preferred to trade when hung over. In his 80s video, the one PTJ is always trying to ban, there is clip where he appears to be drinking from what looks like a can of beer while trading FX on a sunday evening in the US from his home just before the London morning open. So he gave away the real secret to making millions by trading right there, we should all trade while drunk or hung over
Alcohol lowers testosterone in men and alleviates anxiety. That can be beneficial in a risk taking atmosphere. You need to know your limits well though.
I caught that too, perhaps he meant shares. He probably used to selling 40,000 of his GS stock at a time.
