Just sit down and relax. See your trading or investment history from the past 1 to 2 years. From my experience, it is the best approach to know a person character.
Those who consistent winning in their portfolio. They behaved like entrepreneurs. Learn, improve and review. Those who keep making the same mistake repeatedly. Will probably make the same mistake repeatedly.
Your investment strategy is just a mirror to reflect your own character. You may can possibly learn who you are with just a short review to your trading or investment pattern.
