What constitutes a topic in wich you are not interested?

 I would consider  that writing a personal essay is easier than writing about a topic that you are not familiar.When you have to write about our personal lives,we can go on and on because we already know what to write.On the other hand ,it is easy to write about a different topic if we are familiar with the topic.Sometimes is difficult too for me to talk about me . One example, I was assigened to write about my writing skills.It was a personal topic ,but still I did not have enough ideas. I didn't know what to write.

   It is interesting to write whether is a personal or different topic as long as we are familiarized with the topic
