Quote by Karl Popper

"The task is not so much to see what no one has yet seen, but to think what nobody has yet thought about that which everybody sees."

"All life is problem solving."

"Science may be described as the art of systematic over-simplification."

"The more you know, the more you realize you know nothing."

"Friendship is built on trust and honesty."

"True friendship is worth more than gold."

"Good friends are like stars, always there even when you can't see them."

"Friendship means sacrifice."
