I have seen many science-fiction movies about time travel, most of them tended to send the main characters back to ancient times and changed the history. Only a few of these movies were about the future. So, if we plan to travel in time, the first choice we face is to whether go back in the past or visit the future. As for me, both of them appeal to me very much. I have two reasons. First, I’ve always had regrets for not choosing my favorite major after I finished high school. It pushed me to choose a job (which) I really don't like. I really want to go back to the time when I was in high school and start a new life. Second, I love my family, I don't want to change anything in my life. I just want to know if I’m currently making some mistakes which will lead to bad consequences in the future. If I can predict the future and avoid mistakes, my future life will be happy and I’d be thriving without having to worry about annoying things. In fact, none of this will happen. The world just gives us the present, the only thing we can do is to learn from the past and plan for the future. To become the best version of yourself in the future you need to carefully think about your current choices!
