There is a Japanese old saying  like this:

"A fool cannot stop being a fool, until he dies."

If a fool dies psychologically, not phisically, and he/she is re-born, he/she may be able to stop being a fool. Or, after the death and re-birth, he/she can be a smaller fool than he/she used to be before the psychological death and re-birth.

A trader cannot stop being a trader, after the death and rebirth in markets many times.

Musashi says, in "Vagabond", like this:

"A sword cannot stop being a sword."

Neither can a trader.
