Each day our world is constantly changing and becomes more competitive. Good leaders brings their teams toward progress and success. However, what does it really mean to be a good leader? World-class author and motivational speaker Simon Sinek might have an answer. 

Sinek suggests that the key element of inspiring team members to strive and aspire, is one of human's primitive but often neglected needs: a sense of security.

When we feel safe and secure in a group, trust and collaberation come naturally. A sense of security will generally produce these positive effects.

Furthermore, Sinek introduces his concept of "Circle of Safety" to analyze the common leadership problems in modern business management.
