What “everyone else” is doing is not relevant. Unless they’re all doing the right thing. The fact that everyone is doing it is not evidence that it’s the right thing, because people often mimic one another without thinking things through.
If you do what average people are doing, you’ll get average results. If you want extraordinary results you have to do extraordinary things. You have to do what hardly anyone else is doing. If you’re going to copy, copy what extraordinary people do, not what average people do.
It’s also important to stick to what you can understand, while continuing to expand that circle where possible. What do you understand that most people would disagree with you on? That’s your extraordinary niche.
It doesn’t have to be one thing, it can be a few things. But it’s not going to be fifty things. If it’s a lot of things, you probably think you know more than you actually do, or people may not disagree with you as much as you think they do.
