I want to go back in time when I was young.Because when we don't stress or worry very much. Can do no wrong. If be a child, I want to study hard so that in the future will be intelligent and knowledgeable.So I want to go back to a child to think about this to have a definite goal so that we can follow the target, fully and plan for the future as well.Because English is a universal language that is used to communicate all over the world, so I want to good at English. In modern English is important and we have to learn in order to communicate.Childhood is the happiest age and the age of starting to learn. So I could go back in time in the past.
