If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog.
Have in-depth knowledge in your niche? Package it up into an ebook and sell it on your blog. I'd generally advise against selling it (at least exclusively) on Amazon or Kobo, as you'll probably be able to charge much less. If you've already built up a solid audience, you can probably change anywhere from $5 for a very short one, all the way up to $39+.
As an affiliate marketer, you promote someone else’s product or service to your readers. You link to that product or service using your unique affiliate link. When, someone clicks through that link and makes a purchase (or completes a desired action set by the company), you earn a commission. There are thousands of affiliate programs to join.

If you aren’t part of an ad network then you are constantly searching for new companies to advertise on your site. This one was always a pain in the ass for me. I wanted to spend time making my site better, but if I ignored selling my ad space then I wouldn’t have money to continue to make my site better.

Write content. I like to write an article from beginning to end with no breaks. It may take me an hour to write an article or I may be at it all day. Sometimes, content does span a few days, but for the most part, I like to finish a piece of content in one sitting. I then hand over the content to my editor to fix anything from grammar, punctuation, to the general flow of the article. The only thing she doesn't edit is my monthly income report.
