Trading is not for everyone.  There certainly is a high burnout factor among professional traders due to the stress involved.  Think of the markets as various shark tanks, with a certain number of sharks fighting for those scraps of meat.

Some of the work personality traits that will help you succeed over the long run include:

Having a thick skin, being able to remove emotions, ability to think clearly in the moment when all hell is breaking loose, attention to detail, pattern recognition, analytical mind, aversion to gambling for gambling’s sake, creative and innovative thinking.

These can be developed through experience, although some certainly have these more “ingrained” in themselves from the beginning.  Having a full life outside of your trading is also important – the ability to “switch off” and not take your trading results home with you each day will lead to a longer and happier trading career.
