Quote by Johnny Cash

"I keep a close watch on this heart of mine"

"You build on failure. You use it as a stepping stone. Close the door on the past. You don't try to forget the mistakes, but you don't dwell on it."

"I'm just trying to matter and leave my mark for good."

"The greatest gifts are those that come from the heart."

"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."
