I quite agree with you in what you say that nobody understands.
Even people who are connected with the stock market in some way or another believe it is all random.
It is therefore not wise to discuss anything with anyone except within your own circle and thern only with individuals who you know understand because they themselves are also successful traders.
It is prudent not to say anything at all and if pressed to say you are a retired taxidermist or something equally boring to put people off the scent.
You ought to make it a rule never to volunteer information such as giving market tips for example.
You might also consider when you become really successful to opt to walk around in old jeans and old sweaters with the odd moth hole in them, even if they are cashmere, because very few people can tell the difference. It is important never to show off, it makes people envious.
The best lesson I ever recieved occured when I was mugged in London and had my gold Rolex day date snatched. I was fortunate not to have been stabbed. Since then I wear an equally good wristwatch but it does not look expensive, as it is a pilot's watch.
I teach all my people to be very kind to "civilians", who are ordinary people with obligations, timetables to adhere to, jobs to keep and so on, as for us time does not matter since we are free to do precisely as we please.
I also teach them to be "grey men and women" so that they can merge into a crowd and not be singled out as different because of dress, jewellery and so on.
It is very different of course when you are in the right company, in the right place, on the right occasion.
The part played by a wife or partner is extremely important, and her cooperation is this regard is crucial.
The wife or partner of a successful trader also has to play the muted part, and not show off and be conspicuous.
She must be a good hostess, and be able to take everything in her stride, and be prepared to entertain and have some knowledge of what is being discussed about finance or trading or economics or otherwise at the dinner table, in order to keep up more or less.
She ought to also remember the likes and dislikes of individual guests who are regular visitors. She should be supportive of everything the partner does and decides, whether it involves screen watching, travel, entertaining, or conferencing.
Also which is most important she must accept not to ever enter the trading room uninvited, or to interrupt whilst trading is in progress.
If she is able to do this whilst at the same time accepting the wonderful benefits the world of trading can bring, and if she can be trained to do so, this is the ideal state, whilst still being her own person, and independent.
The wife or partner of a trader ought to be made financially secure and independent at the earliest possible, in order to remove the burden of dependency. She must be encouraged to have interests to keep her occupied, coffee mornings, hobbies, friends, and so on.
Only then can she feel confident and assured and be an asset to her partner and not a hindrance.
I can tell you all these things because they are part of my own life. They are the desired state for anyone who becomes successful in this field and is even more important on the road to that success.
