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 fourth, that it does not have a definite color;
The fifth, that it sings very softly.

– San Juan de la Cruz –

いちどに道路ぜんぶのことを考えてはいかん、わかるかな？つぎの一歩のことだけ、つぎのひと呼吸のことだけ、つぎのひと掃きのことだけを考えるんだ。いつもただつぎのことだけをな。

「モモ」- ミヒャエル エンデ –
