You can have anything you want if you want it badly enough. You can be anything you want to be, do anything you set out to accomplish if you hold to that desire with singleness of purpose.

Focus beats wanting anything badly

There's a version of this quote that gets repeated at every motivational seminar: want something hard enough and it's yours. But what Lincoln is actually describing is much more specific—and much harder. He's not talking about desire alone, but about "singleness of purpose," which is a different animal entirely. It's the difference between wanting to be fit and actually showing up to the gym on Tuesday morning when it's cold outside.

Most of us operate with scattered focus. We want better careers and better relationships and better health simultaneously, pulling our attention in different directions. The real constraint isn't our capability—it's our willingness to be boring about one thing long enough to actually get it. Lincoln's point cuts against how we're built: we naturally want everything at once, without sacrifice. But singleness of purpose means choosing what matters most and letting other things slide for a while. It means being willing to be one-dimensional for a season.

The slightly unsettling part? Lincoln isn't promising this is easy or that it feels good. He's just saying it works. You'll have to give up other things. You'll get bored. Other people might not understand. But if you actually want something—if you can maintain that focus without diluting it—the obstacle isn't external. It's just waiting for you to prove you meant it.
