Consider the following examples:
1) The diligent hard worker who periodically burns out and fails to maintain valuable friendships and personal relationships;
2) The process-oriented trader who develops good trading habits, but fails to innovate and expand those habits;
3) The trader who processes information very well through teamwork and social interaction, but who falls prey to consensus thinking;
4) The caring manager who has great relationships with employees, but avoids conflict and does not effectively uphold work standards;
5) The trader who is passionate about markets and learning about trading and who loses money by overtrading.
In each case, a strength carries the seed of its own undoing: what powers us down the track can also derail us.
It’s a good exercise: list your top three strengths as a trader and then clearly identify a dark side to each that has, at times, derailed you. You’ll wind up with a pretty good list of best and worst practices that can feed your self-awareness and guide your trading process.
