The third excuse that writers create for themselves to not write is that it has all be done before.
This is an interesting angle. It is true that every single topic has probably been explored. However, should that stop you from writing about it? I don’t think so. We each have a unique vantage point and if you are able to offer a new perspective, then you should definitely go ahead with your idea. If you take the example of diet books, that has certainly not stopped people from writing more and inventing new diets almost very day. And as long as people will have an interest in weight loss, then more diet books will appear. I am not saying it is right. It just is.
Take the example of diaries. There are many books in that genre but you can always find a new angle. I loved the secret diary of Adrian Mole. That didn’t stop me really enjoying Bridget Jones’diary. Why should it? There can be travel diaries. Eating diaries (why not, that could be an interesting variation to cook books). Knitting diaries. Pregnancy diaries. I used to write a blog called the tiara diaries. How about the diary of a primary school teacher. The limit is your imagination, which in other words, means there should be no limits. Because at the end of the day, your reader wants one of three things: information, emotion or entertainment.
All you need to be is authentic.
