The drastic pull from comfort zone

I've been writing under entertainment for ages and boom! I got pulled out of entertainment and landed in boring articles. okay maybe not boring but the point is, I get to write about things I have never given attention to or even read about. my first two weeks was a disaster and my lovely job was starting to frustrate me, in 2 weeks, I published only 3 articles on the said topic. very low productivity and every day, my babe ( smiles sheepishly) was encouraging me, I had to start doing comprehensive reading and studying like I was in college again but it worked some, and online tools also worked. what I'm trying to say with all these gists is that every writer has a niche right but is it okay to have a hang of other stuff, yes you should, and should you be everywhere? no, you shouldn't. I3 still love entertainment writing, it is still my niche, and creatives is still my thing but for now, I'll learn this and just move on.
