What is it that I want to write?

What should I write about when I am searching for a topic to write about?

I could pause and feel the topic at the moment.

I could search my memory for a topic which I had thought of before.

I could start off a topic which I've planned to write when I have time.

I could always write something on a topic that relates to my personal encounters.

Also, I could always improvise.

And, I could always be randomly creative in my thinking of which I transform it to writings.
