Life is not about making others happy. Life is about sharing your happiness with others. Imperfections are important and so are mistakes. You get to be good by learning from your mistakes and you get to be real by being imperfect. When you try to control everything, you enjoy nothing. Life is like a rainbow, you need both the sun and the rain to make its colours appear. So similarly, be it an exam or a teacher, only through the journey of your life, you explore so many wonderful things...!
