Reprove your friend in secret and praise him in public. - Leonardo da Vinci

I have seen motions of the air so furious that they have carried, mixed up in their course, the largest trees of the forest and whole roofs of great palaces, and I have seen the same fury bore a hole with a whirling movement digging out a gravel pit, and carrying gravel, sand and water more than half a mile through the air.

"Gustavo Solivellas dice: "Los hombres geniales empiezan grandes obras, los hombres trabajadores las terminan" (Leonardo Da Vinci)"

One shall be born from small beginnings which will rapidly become vast. This will respect no created thing, rather will it, by its power, transform almost every thing from its own nature into another.
