“What really happened doesn't matter. What matters is how we agree to remember it.”
“What matters in life is not what happens to you but what you remember and how you remember it.”
“It doesn't matter what did or did not happen then. It only matters what happens NOW.”
“It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong.”
“It doesn't matter what we are. It matter what we do.”
“It doesn't matter what we choose. It simply matters what we are.”
