The conditions of a solitary bird are five:

The first, that it flies to the highest point;

The second, that it does not suffer for company, not even of its own kind;

The third, that it aims its beak to the skies;

The forth, that it does not have a definite colour;

The fifth, that it sings very softly.

SAN JUAN DE LA CRUZ, DICHOS DE LUZ Y AMOR

We choose only once. We choose either to be warriors or to be ordinary men. A second choice does not exist. Not on this earth.
