@NerdyKeith That’s very helpful. Lifestyle is a good topic that allows you to branch out into many different interesting areas. You’ve mentioned 3 good ones to start with. Vegetarianism is huge. You can talk about the impact it has on the environment, and there are all the recipe ideas you can explore. Healthy eating seems like a tangent from vegetarianism. Exercise is also very good. There are so many ways to talk about the plethora of exercise opportunities all around us.
You can even go further with lifestyle. There’s fashion and fashion on a budget. You can talk about restaurants from high end to holes in the wall.
Relationships are a part of lifestyle. Meeting new people is often the topic of discussion online.
Good luck!
