“The Universe is very, very big.It also loves a paradox. For example, it has some extremely strict rules.Rule number one: Nothing lasts forever.Not you or your family or your house or your planet or the sun. It is an absolute rule. Therefore when someone says that their love will never die, it means that their love is not real, for everything that is real dies. Rule number two: Everything lasts forever.”

“The rule for working out prime numbers is very simple, but no one has ever worked out a simple formula for telling you whether a very big number is a prime number or what the next one will be. […] Prime numbers is what is left when you have taken all the patterns away. I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them.”

“Love changes everything. Days are longer, words mean more. Love changes everything. Pain is deeper than before. Love can turn your world around, and that world will last forever.”

“I'm saying with very few exceptions nothing lasts forever, and among those exceptions, no work or thought of man is numbered.”

“Svava: "Rule number one: Never make a fool of yourself."Riis: "Rule number two: Never be a burden to any one."Svava: "Rule number three: Always be in the fashion.”

“You cannot convince people to love you. This is an absolute rule. No one will ever give you love because you want him or her to give it. Real love moves freely in both directions. Don’t waste your time on anything else.”
