Lao-Tzu, the ancient Chinese mystic philosopher, wrote that in the 6th century BC. Modern-day authors might say something along the lines of “effective leadership starts with knowing yourself”.
The corollary of these quotes might read that “lack of self knowledge is unenlightened and can result in poor leadership”.
I know from personal experience, running leadership workshops, that most people can reel off a list of past bosses who have disenfranchised and demotivated all and sundry.
For many, the soft skills of leadership and team working just do not come naturally. Often, individuals are mortified when they discover the negative impact they are having on others. Fortunately, there are routes to enlightenment and it is generally accepted that soft skills can be taught.
A good place to start can be the Myers Briggs Type Indicator, which uses behavioural preferences as a way of describing an individual’s personality. Other psychometrics such as the 16pf explain personality in terms of observable behaviours while 360s provide feedback from peers, reports and your boss.
All of thee tools can be a small step on the road to enlightenment.
