New Year

Hello Rabbi. From my acquaintance with you, I remember that you are less concerned with topics like: “What is the essence of this and that holiday, and how to prepare for the holiday, etc.”
However, I would be happy if the Rabbi could please give some advice on how to prepare for the terrible Day of Judgment?
And also to know, what is our work actually on Rosh Hashanah?
And does the Rabbi know of any books that convey content about these days in a logical and rational way that would provide something to learn from in a good way?
 
Thank you very much, Rabbi, for getting to know me since the beginning of 2018. I learned a lot from you, and I really, really appreciate it. Good writing and signing to you and your entire family.
