There has been a lot of debate on whether people should be specialists, generalists, or whether they should "be the niche". Here's my take on it: Specialization is the fast-track to riches, but "being the niche" is the fast-track to fulfillment/purpose: Writing, reading, thinking, and teaching is a worthwhile lifestyle. The 3 theories of audience creation: Broad: Communicate all interests. Specific: Communicate one singular interest. "Being the niche": Communicate one singular interest for 3 months before pivoting. Why you should "be the niche": This theory combines the benefits of both broadening and specializing. You can follow your interests whilst not diluting your brand, but instead, building upon it. Instead of knowing one area extensively and suffering the effects of the Law of Diminishing Returns, you can learn 80% of a topic of interest, monetize your knowledge (also teaching 80% of what people should know), and follow a new interest. Why be an expert in skincare but know little about fashion? If you learn about fashion, why not teach others what you learn? Odds are, you won't be interested in the same topic for years on end. (And neither will your audience be). Why talk about something you no longer care for? When you talk about one topic deeply for a ~3 months before switching, you build a portfolio of content. Additionally, you'll also become an expert in 4 things every year. By being an expert in multiple topics, you can also connect the information and create unique perspectives.
