Try to defend your argument. Why do you say things? Because you heard they are trendy nowadays. Is this your opinion or is this supported by other sources? How do you know this is relevant to your project? Did you do research, i.e.: literature reviews, or data-gathering questionnaires, or is this based on your own gut feeling? You need to explain everything you state or every notion you share. If you cannot provide a citation, it is only an opinion, and an opinion has no academic value. You may be 100% correct, however for your academic work to carry credibility you have to convince the reader you know what you are talking about – therefore you have to reference everything you say.
Even though this might be the opinion of the author, you can and would find resources to support your reasoning, especially on the topic you are researching. REMEMBER: Do not use the term 'the opinion of the author', or 'the opinion of the researcher', or 'the researcher believes', at all. There is enough literature that can be cited to support your arguments. You need to provide support from the literature for your arguments. ALSO REMEMBER: You are not with the reader to explain to the reader what you mean when the reader has questions. Therefore, it is important for you to provide the reader with all the information the reader needs, backed by authoritative sources (citations).
