The reason you should NOT write

There is only one reason which should not be your motivation to write, (other than when you're writing a suicide note/a murder note/you're writing energy is channeled into destroying the world muahahaha!) oops just revealed my master plan.
Anyway that reason is to become famous. Honestly if you get no joy from writing and only want your books published so you can become rich and famous then GTFO (get the fuck out).
Chances are it probably won't happen to someone like you, there are so much more deserving writers who are yet to be published, or are self-published, or have been published traditionally yet slip under the radar.

Also here's a reality check: only a very small number of writers actually become rich. Most writers, even those who have been published traditionally, maintain another job to live comfortably.
See if your reason to write is so you can become published then I perfectly understand. It is always a dream of a writer to become published traditionally, and many go through self-publishing and marketing themselves on social media websites to eventually actualize their dream.
However if you want to become published so you can become rich and famous, then chances of that ever happening are pretty low. In fact working an extra shift at work and being a miser would be an easier and more effective way to become rich.

If you don't enjoy something, then don't do it. Simple as that.
