A pleasant morning to all my friends who are present here. As we are aware, today is voting day. The fact that you are here shows that I have your support.
The decision to contest the student council election was challenging. But If you aspire to help the people around you, solve their problems and work for their interests.
A school provides the first opportunity to give wings to your dreams.
We all are fortunate to study in this excellent school where students have ample opportunities to explore, expand and excel.
Being a student takes work; becoming a school leader will take a lot of work.
But I assure you, if I win the majority votes ,I will work for the benefit of all of us.
