I want to write, having a laptop, makes, me want to write, but I don't want to pay $98 for subscription for word, but I also don't know what to write?

On ebay or amazon you can probably find older word processing programs like MicroSoft Office 2003, 2007, or other years. You should get a CD and a product key.

Your PC would need a CD drive of course.

I bought MS Office 2003 professional edition when it was new back in 2003 for $500 and still use it on whatever computer I run, to this day.

BTW, on ebay, some of the older MS office programs are as cheap as like $30 for the student edition.
YOu do not really need anything new because they all work the same.

You can download LibreOffice, save the $98 and write about that. :-)

Actually,I do my best writing with a pen and paper

Wordpress has free blogging site.
