Today, make a list of unpopular opinions you have. Maybe you have an unpopular opinion because someone told you it’s an unpopular opinion, or maybe because you cannot stand something that everyone else seems to love, or maybe you have a very good reason for seeing something through the lens of personal experience and nobody else seems to get that. Nobody needs to see this list unless you decide otherwise, so really let it rip. This can range from tv shows and movies to socio-political ideas to pop culture to a missing narrative in history. Whatever it is, own it and get it on the page.
Now, pick one and write about it. Tuck the other ones away on your main ideas list for another time.
