Seniority does not always mean superior knowledge and skills
To belittle someone is a cover-up of one's own inferiority
Putting down your colleague is a desperate move to lift yourself up
Lifting your own chair is bad, patting your own back is worse

An effective section head is one who uses her head with a big heart
Constructive criticism help a weakling grows to a better person
Intelligence cannot be faked, it just shows naturally
Accepting correction is next to perfection
