A good thought:
As a blogger don’t feel pressured to only blog about one thing, one category, or one reductive thing. Instead, best to indulge your interests as far and wide as you want!
For me, all knowledge is inter-connected. This means if you truly want to plumb the deepest depths of knowledge and to gain deeper wisdom and understanding about society, humans and the world, you must study it all, share it all, and write and reflect on it all!
