You could work on becoming a tea expert.
If you started a website on all things tea, and wrote the answers to the questions people had about tea, you could bring in some website visitors to your website. Then you could recommend teas to people and earn affiliate commissions.
I would try out Ubersuggest.com, and go to Keywords > Keyword Overview, and enter tea (for English, United States), then Search.
Once you receive the search results, go to Keywords > Keyword Ideas, and sort the results by SEO Difficulty (easiest to hardest).
This will show you some phrases that people are searching for that are easier to get website visitors for.
