I happen to believe that critical thinkers have less conceit – and that doesn’t mean their actions are completely blemish free.
Obvious aspects of stability in today’s society are perceived to be style, physical appearance, and financial strength. But the most important aspects of stability (which frankly not many people have) are: state of mind, confidence, listening attitude, and introspection.
Just because some people are doing all the talking doesn’t mean they are the most stable. And remember: if someone "seems" to be stable today doesn’t mean they will be so forever, or tomorrow for that matter.
Human-beings are extremely social, insecure, and susceptible. Unfortunately, this could lead many of us to attach importance on other people’s opinions. So it becomes easy to go from super-stable to flat-out unstable. In my view, reasonable volatility blended with introspection is not a negative trait.
The secret to survival is to question and critic yourself -but- not give damn when others question you!
