For making school a happy place, first of all, be humble and nice with everyone. respect your teachers and friends and talk obedient. and most important, put your mind mainly in studies and always so everywork sincerely. if we are all rounder then everyone will like us and we will be spending a good and happy time in school. sometimes we should enjoy also, and take part in co-curricular activities for our happiness and fun. and last but not the least, keep smiling.
