really need a person's help

[Wendigorzoott]

I like to get my inspiration from really meaningful phrases said by truly great people like “If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things”, do you know where I can find thematic compiltaions of those?
