They're all lessons I've learned 
from my own failures.
.كلّها دروس تعلّمتها من محاولاتي الفاشلة
von Fehlern, aus denen ich gelernt habe.
los aprendí de mis errores.
los he aprendido de mis errores.
sono frutto di ciò che ho imparato
dai miei fallimenti.
São lições que aprendi com
meus próprios fracassos.
Я уяснила
из своих же ошибок.
