Quote by William James

"The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind."

"Act as if what you do makes a difference. It does."

"The only way out is through."

"Does consciousness exist? I say yes."

"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."
