To look professional during an interview, you must wear modest and professional clothing (a suit). It is rude to not pay attention to the interviewer when they are spending time out of their day to talk to you.
When developing the paragraphs in an essay, the writer should include the information about the sources for all quoted information to avoid plagiarism. Some of the information you used in your essay to support your topic are just borrowed ideas and you are just using them as basis and reference and does not originally come from you. Therefore, to avoid plagiarism, quoting them is very essential to give credit to the person who came up with that idea.
In the future I would like to become a successful author both with my present book and hopefully with future books since I believe writing will become a more and more enjoyable activity. While I am 72 years old now, I don't think of this as being that old and hope I may live to be at least 95. I will definitely need significant more time to fulfil my dreams now that I have matured and learned the true meaning of life. I also will wish to travel around the world in the future before I get too old to move much.
