"Intelligence is the most important human trait"

"Personality is determined by genetics and environment in equal measure"

"Neuroticism is a predictor of psychological distress"

"The best person is one who scores high on extraversion and low on neuroticism"

"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."
