For me, it's not about price. It's about necessity, quality, and usefulness. Like, I have my Wet N Wild 666 lip liner. It's 99 cents and always has been. I started using it when I was in high school, and it's great.
But if I were to say who influenced me most, then I'd say Franz Kafka. And his works were always anchored in the Central European region.
The science of the mind can only have for its proper goal the understanding of human nature by every human being, and through its use, brings peace to every human soul.
