/skil/ – noun – the ability to do something well; expertise.
You’ve set a goal, and you see these “big” obstacles.
Maybe you’ve got an intense negative emotion about them, or maybe you don’t even think you can do them.
Unless you physically cannot do it, you’re lying to yourself.
The truth is, you’ve either got a belief about what it will be like to do this thing (we’ll go over why that is), or you’ve never done it before and have no valid data.
