Not one, but three books that are life changing.
Me matan las ganas...
One Thousand Splendid Suns _Khaled Hosseinni
It gave me strength to endure the mistreating I was putting up with.
Man's Search for Meaning - Viktor Frankl
It made me appreciate and see the silver lining in dark situations.
Anthem - Ayn Rand
By far the best book, made me understand my power as and individual.
