To blaze a trail...
Is to know that "There is no path, the path is made by walking" (http://minimo.50webs.org/caminante_eng.html)
It's to know that the next step will always be difficult.
It's to know that you will never walk the normal path.
It's to be different.
Blazing a trail is hard. You will get lost, and you will trip over.
Your only option is to continue forwards, for the sake of the people that follow your trail.
By moving, by going, by doing, you become correct. You become the authority. You become the trail.
People follow trails, because that's what they do.
Blaze a trail. Be a trail.
