"Persistence is the path to success."

"The world of science and mathematics does not discriminate based on gender."

"I have penetrated into the essence of things and perceived that to solve the great problems we must change our way of thinking."

"Nothing is better able to guide us through life than to accustom ourselves to a fair examination of our own hearts."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
