My Topic Struggle

I am not sure what my topic is. I am still having trouble deciding. It is between writing about idols or about games.

I can talk about the difference in the entertainment industries amongst America and the Kpop industry.

The other topic is about gaming and how the gaming industry is popular these especially certain games.

I have always been interested in these topics and I thought I could try writing something new.  Instead of writing about common issues, I can try writing about topics that not a lot of authors write about.

Now, I am stuck because I don’t know which topic to write about. Both of them are really good.

I am struggling and I need help. Any suggestions?
