The ability to “reflect over” his own actions and behaviour is a very important quality a Trader needs. Being reflective helps someone to be able to look into his life and ask himself questions like his motives and intentions over the decisions he made.
The next ability which is equally vital for Traders is, the ability to take the appropriate action to improve himself after reflecting over whatever past experience he thinks requiring improvements. I use the word “appropriate action ” rather than the “correct/right action” because there’s no right or wrong but only consequences.
