Many high school students are under so much competitive pressure. They are sometimes taught that if they don't have a 4.0 GPA, score in the 99th percentile on admissions tests, and demonstrate leadership in sports and participate in clubs, they won't get into college anywhere. Even highly credentialed professionals get caught up in this.

To be an objective leader means aligning your models with the needs of the organization. There is no question anymore that collaboration, seeking out diverse perspectives and developing new ways to look at challenges and opportunities, is a key leadership competency.

Objective leaders identify their unproductive mental models and tweak them for greater effectiveness.

We perceive through our senses a person, a situation or an event, and in an instant, we project our mental models - our fears, background and experiences - onto that perception. This often results in cognitive errors, which means we judge and respond incorrectly.

Good leaders organize and align people around what the team needs to do. Great leaders motivate and inspire people with why they're doing it. That's purpose. And that's the key to achieving something truly transformational.

It's amazing that people were talking about me as a future leader back in 2011.

At the end of the day, people will follow you or people will be energised by you if they buy into your vision or purpose. So the most important thing is to be true to yourself. That's why I would say to be a great leader - you, first and foremost, have to be a great human being. And sharing that purpose and sharing the values.

Social media is itself as temporary as any social gathering, nightclub or party. It's the people that matter, not the venue. So when the trend leaders of one social niche or another decide the place everyone is socializing has lost its luster or, more important, its exclusivity, they move on to the next one, taking their followers with them.
