The most successful traders I know are supremely confident. Ultra-confident, even. But do not confuse the emtions of cocky, bravado or arrogance (aka over-confidence) as they are all just social masks, manifestations of fear itself. In other words, all successful people are extremely confident in their ability. If they pretend to be anything otherwise, it too is just a social-mask projection.
As long as your giddiness does not overrule your risk profile, then be as confident as you want........ Education of a Speculator. Commit this book to memory.
