In the seminary, Imam was always present in the class at exactly the time he had arranged it. This was clear that he would be annoyed if we were late for lessons.
He was not just a teacher, but a role-model for his students and taught us many lessons for life. His self-discipline and punctuality were exemplary as he used to advise us on valuing our time as much as we lived a life of seminary.
If you are going to achieve success and positions of high significance in your life, you need to care about time management for different jobs you are tasked with, he recommended us at the class.
