“Life is like riding a bicycle. To keep your balance you must keep moving. —ALBERT EINSTEIN, IN A LETTER TO HIS SON EDUARD, FEBRUARY 5, 1930”

“Throughout his life, Albert Einstein would retain the intuition and the awe of a child. He never lost his sense of wonder at the magic of nature's phenomena-magnetic fields, gravity, inertia, acceleration, light beams-which grown-ups find so commonplace. He retained the ability to hold two thoughts in his mind simultaneously, to be puzzled when they conflicted, and to marvel when he could smell an underlying unity. "People like you and me never grow old," he wrote a friend later in life. "We never cease to stand like curious children before the great mystery into which we were born.”

“When you write biographies, whether it's about Ben Franklin or Einstein, you discover something amazing: They are human.”

“If you just sit and observe, you will see how restless your mind is. If you try to calm it, it only makes it worse, but over time it does calm, and when it does, there's room to hear more subtle things - that's when your intuition starts to blossom and you start to see things more clearly and be in the present more. Your mind just slows down, and you see a tremendous expanse in the moment. You see so much more than you could see before. It's a discipline; you have to practice it.”

“You should never start a company with the goal of getting rich. Your goal should be making something you believe in and making a company that will last.”

“I visited Jobs for the last time in his Palo Alto, Calif., home. He had moved to a downstairs bedroom because he was too weak to go up and down stairs. He was curled up in some pain, but his mind was still sharp and his humor vibrant.”

“By then Einstein had finally discovered what was fundamental about America: it can be swept by waves of what may seem, to outsiders, to be dangerous political passions but are, instead, passing sentiments that are absorbed by its democracy and righted by its constitutional gyroscope. McCarthyism had died down, and Eisenhower had proved a calming influence. “God’s own country becomes stranger and stranger,” Einstein wrote Hans Albert that Christmas, “but somehow they manage to return to normality. Everything—even lunacy—is mass produced here. But everything goes out of fashion very quickly.”9 Almost”
