Trading has taught me different things about myself at different times according to how the situation has gone. It has taught me that I can be very disciplined, that I don’t have to have external constraints imposed on me. It’s taught me that I’m very self-reliant. Often I can put together the jigsaw puzzle, even though some pieces are missing and will have an insight into a trade that other traders don’t perceive. Sometimes I realize I’ve been arrogant in the way I’ve done something.

It’s interesting how trading teaches us something about ourselves that we don’t necessarily want to know but the information is always very instructive.
