WHATS THE BEST NICHE TO BLOG ABOUT?

Hello steemians, I am Hive account@teslim and I'm new on steemit. I have been trying everything possible to grow on here and I hope it will soon be realised with you guys help. Since my cousin Hive account@epikcoin introduced me to steemit and Hive account@honourmaus put me through some things on steemit I have been blogging about a bunch of random stuff which I think is cool to me but I would like to focus on a specific niche because I don't want to be a Jack of all trades, master of none sort of a person.
Most books I've read on blogging suggests that the first step to a successful blog is to pick a niche that you're passionate about, but that seems difficult for me because there are a lot of things that interest me in no particular order. Talk of sport, entertainment, photography, events, travel, stories, creative stuffs, sentimental stuffs, current affairs, I love motivating people too and a whole lot more. yes I am definitely into everything and I'm everywhere.
The second step to a successful blog is that you have to be consistent. Always update and never disappoint your audience.
The third step is to get to know your readers. I know a lot of ladies has little or no interest in sports and politics, so if I'm to focus my blog on sports and politics, I will lose some of my devoted female audience. I know ladies does love things that has to do with fashion and gossips and maybe love stories too. I know young men like me will prefer sports and maybe entertainment too. Our daddies like current affairs and politics, but is there some way to please everyone because it is ike impossible to have a niche that appeals to everyone, so I think it's impossible to focus on a specific niche and at the same time keeping everyone interested.
