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."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
