This may be a start. I wrote it many moons ago:
Iyanla Vanzant is a writer, philosopher, poet. I first became aware of her through In The Meantime, described by Amazon as follows:
According to author and inspirational speaker Iyanla Vanzant, being in the "meantime" means being in a state of limbo. "When you are not happy where you are and you are not quite sure if you want to leave or how to leave, you are in the meantime," she explains. Rather than wallow in confusion, Vanzant encourages you to use the meantime as an opportunity to prepare yourself for true love. The first order of business is to clean house, starting with the basement--the place in the psyche where you store your most destructive thoughts. Room by room, Vanzant takes you through a metaphorical cleaning of the soul. This way, when your meantime days are over and love finally comes knocking on the front door, you'll have a clean house to welcome love into.
Even though this is directed toward those with relationship problems, I saw that this had to do with far more than relationships with others, that it also had to do with the relationship with the self and with reality.
Reality is what one perceives it to be, and one's self is also what one perceives it to be. Since our perceptions are affected to an enormous degree by the language we use to describe them, our success in negotiating our way through the world depends on the language we use.
For example, if we use the language of failure, incompetence, futility, stupidity, worthlessness to describe ourselves, we will then fail, behave incompetently, etc. If we use the language of hostility, selfishness, anger, depravity to describe the world and those who inhabit it, then that is the world we will find. In order to change himself, the individual must change the language he uses to describe himself. In order to change the way he interacts with the world around him, he must change the language he uses to describe that world.
The message for traders is clear. If one wishes to be successful, he must use the language of success. He must not, for example, review the day's work in order to drive home all the many ways in which he failed but rather to detail -- objectively and unemotionally -- all mistakes and successes with the goal of determining why the mistakes were made and why the successes were successes, the goal being to repeat those behaviors which were successful and extinguish those that were not. The language one uses is based on "I can do this", not on "Here I Go Again" (for the latter, see Eric Berne and Games People Play). If this is not yet clear, substitute the word "success" for the word "love" in the above description of the book.
"Lessons are repeated until they are learned" is the response given whenever someone begins yet again to repeat the same old destructive thoughts. For instance, the question "why do I keep dating losers" elicits this response. A trader, on the other hand, might ask "why do I keep buying the wrong stocks at the wrong time". Answer: lessons are repeated until they are learned; that is, when one stops buying the wrong stocks at the wrong time, the lesson will have been learned and it won't likely have to be learned again; until then, the lesson will have to be learned again and again and again. And it may never be learned. The truly clueless may go bankrupt first. But until the lesson is learned, the behavior will continue.
There's a lot more to it than this, of course. If you're really interested in it, you could take the philosophical course and look at it in terms of perception and reality, theories of knowledge and existence, and so on. Or you could take the psychological course and read up on autism, phobia, schizophrenia. Easier, though, is to buy In The Meantime and substitute "trader", "success", "stock" and so forth for the relationship words used in the book.
