Hi, If you are passionate about writing, then there should be something that you enjoy more to write about. You will be writing a lot, so it should be something you would like to know about. I would recommend you simply decide with one and press forward with that. As long as you make your writing interesting to you, you won't get bored in any niche you chose.
If you are worried about making your business very profitable, I would recommend using affiliate links for expensive products within any niche you chose.

Hi am I finally speaking with Jesus..girl ha ha, my answer to your question is both,its really quite simple. What do you love doing find really easy, enjoy talking about, that's the niche for you. You say you love writing, write about you and your story, how you came to find WA ,because I guarantee no one has had exactly the same experiences as you.
So start the training and follow the steps doesn't matter your exact niche right now just start writing about yourself, right away, in the about me section of the training, go with it, that's what I did. My journey has been quite a rough one bruised physically and mentally by life, but I turn those negatives into positives and use those hidden life experiences. Now. I was holding back, some of the worst detail, my struggle with my career, my failed property business, divorce and subsequent debt. Which paths shoud I take. It's all relevant.
There is something that only you do best, that you can talk about endlessly, give yourself that chance. Niches are in everything you do. So do think but not too much, research you. Then this isn't even work.
I thought I would stop 'working ' today after about six hours of reading and writing (and punctuation) I might add, trouble with the spell checker.
So I put my feet up with my wife, kids in bed, to Netflix and chill as they say, my wife had to mildly insist I stop working as my mojo was in full swing. I laughed inwardly as the film started...
It was called Horrible Bosses I though 'research' you see this was entertainment that could actually help me blog as a WA affiliate. These guys in the movie took it to the real extreme hating their 9 to 5 jobs so much they were prepared to have their bosses killed. Now I'm not suggesting for a moment to advocate that..although there was this one Manager...No seriously. No niche. sell yourself and WA while your at it. You can learn how to monetise your website later. Work on the platform learn how to add links and promote yourself because you are your best asset, the practice will have you ready when those great ideas drop. Just keep moving forward it may seem slow at first, but we all know you can't pull away in fifth gear... don't we ?

Thanks so much!! I tried to go to your site but it said it couldn't be reached. Well, Ive been through some really rough things myself. Abuse, jail, stripper, drug dealer, single mom and now saved by the Grace of God.

All I do now is raise my 2 kids on my own and chase after Jesus. I love Bible Prophecy and Im also a prepper for the end times. Im also a waitress and a nanny on the side to bring in enough income to support my kids. I dont have much time for anything else but work. So not to sure what my niche could be. And the training said I need to pick a niche that solves a problem for somebody, and to pick a niche where people are actively looking for products and services that they are willing to pay for.

I just dont know what that is!! Thank you for all your advice!

God Bless!!
