Before I grew my wings out, one of my friends always said this one to me:

Nada te turbe;
nada te espante;
todo se pasa;
Dios no se muda,
la pacïencia
todo lo alcanza.
Quien a Dios tiene,
nada le falta.
Solo Dios basta.

It kept me good through a lot of interesting... I had an interesting childhood.
