However, going back in time may also bring more confusion and uncertainty. We may fall into an endless cycle, repeating the same mistakes over and over again, and eventually lead to our mental breakdown. In addition, going back in time will also affect our views and expectations of the future, because we already know what will happen.
Although going back in time can bring us some benefits, we also need to accept the facts of the past and move on. After all, going back in time is just an imagination, and the problems we face in reality need to be faced and solved.
I hope my answer can help you!
