I want to write an প্রবন্ধ but what should I write about?

I am kind of a newbie here but I read many fantastic প্রবন্ধ and since I have not create one,I want to try...Can আপনি guys suggest what I should write about?I was thinking something simple is the best...Since my English is only a normal standard,so I hope that that kind of প্রবন্ধ can make use of my standard English.Thank আপনি for answering😃
