Paulo Coelho said this quote

“ Warriors of light always have a certain gleam in their eyes.They are of this world, they are part of the lives of others, and they set out on their journey with no saddlebags and no sandals. They are often cowardly. They do not always make the right decisions.They suffer over the most trivial things, they have mean thoughts, and sometimes believe that they are incapable of growing. They frequently deem themselves unworthy of any blessing or miracle.They are not always quite sure what they are doing here. They spend many sleepless nights, believing that their lives have no meaning.That is why they are warriors of light. Because they make mistakes. Because they ask themselves questions. Because they are looking for a reason - and are sure to find it. ”
