To serve but not to be served

The Director Kacheera Modern pls
This person is the owner of this school. He told me that before he had started this school, he was a teacher at a certain school and later he developed a culture of to serve but not to be served which made him commenced or started his own asset. He had a vision of promoting quality education in his school but the parents made him fail because they did not perform their work clearly. that is some of them failed to complete the school dues which would have been used in buying necessities in the school.
This therefore resulted into a failure to his ideas.
