Foodie

I have started blogs a few times over the years, but I only have lasted a week or so and then I quit. I've done it maybe three or four times. It's always about food. One time I started one and I was going to try to eat only local food for a month, a year. I had other ideas too. I didn't know anything about it but wanted to write. I still want to write and think blogging will be a great way to do that. I have so many ideas I want to write about. All surrounding food and eating local and being a vegetarian and food sensitivities and being gluten free and politics of food. I could go on and on. Should I focus it down, simplify it or can I just blog it all?
