Quote by Bill Gates

"The world is not fair; get used to it."

"Life is not fair; get over it."

"If you are born poor it is not your mistake, but if you die poor it is your mistake."

"Don't compare yourself with anyone in this world. If you do so, you are insulting yourself."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
