People have different interests which change with circumstances;they also depend on age too. For instance when I was a child I wished to be a driver being passionate of vehicles and as time went by and circumstances changed I wished to be a doctor ; again knowing that a teachers job is really a service to the society and being a good teacher is something great I chose that profession. Similarly in my childhood I had more girlfriends than boy friends while during teenage under certain circumstances boyfriends were more and when married my best friend is my wife.But my advice to the students is that they should have an ultimate aim based on their good interests and achieve it even though circumstances are negative,
