What do Teachers Doctors Farmers and Soldiers do?

The question is that who serve the country best, According to my opinion teacher can serve the country best. because teacher is that profession who teaches other professions. On the other hand we can say that teachers are the nation builder, a saying about teacher is that, It takes thousands of workers to make a castle; Billions of soldiers to protect our country; Millions of stars to make a shinny sky; But a one person who can make the future of person brilliant is"TEACHER". If we talk about any profession such as doctor, dentist, engineering, pilot, policeman or many other but the reach at that level only because of teacher. So teacher are best.
