I found this video last night and I was really impressed, because Simon Sinek gets it. He understands and clearly conveys what a leader truly is. From an A-10 over Afghanistan, to the chemicals our body produces and why, Simon talks about why we get addicted, or feel good when he help others, or are helped, or even watches one person helping another.
He talks about endorphins, dopamine, seritonins, oxytocin and cortisols, and why they are produced and what they do for us.
The most important thing he talks about is being a leader. Again, he gets it. Alphas eat first, because they are the biggest and strongest of us. Out of those Alphas, the ones who make sure everybody eats and feels safe in the group are leaders. CEOs who unflinchingly sacrifice hundreds of jobs to preserve quarterly earnings (and his annual performance bonus) are not leaders. A cleaning supervisor (head janitor) at such a company, if he truly looks after safety and well being of the people he is responsible for is more of a leader than the CEO.
Leader is a title that cannot be given you by your job or position. It can only be earned by your actions of selflessness and concern for the entire group you belong to, be it your family, the company you work for, the society where you live, your country.
Take heed about why you should talk with someone face-to-face (or over the phone if you can't see them) after they send you an email asking your opinion about something. If we all did things like this, the world would be a better place.
Watch it, you must. Learn and enjoy.
