The American culture emphasizes working hard, and that is indeed something that makes America great, however, it's always important to remember a subtle point.<br><br>There is a remarkable story about Marcus Chown asking Feynman to tell his mother to study physics.  Feynman writes her a letter saying, ""Dear Mrs Chown, Ignore your son's attmpts to teach you physics. Physics is unimportant. Love is. Richard Feynman."<br><br>Einstein said, "A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving."<br><br>Between Einstein and Feynman, is it hard work or love that matters?  <br><br>It's interesting that the hardest work Einstein did was as a patent clerk!  <br><br>Sir Ken Robinson, in his many TED talks, tells us that when we love something, it doesn't feel like work.<br><br>What is sometimes underappreciated is the value of diversity.  In diversity we find what we love enough to do it seamlessly, which is why Feynman emphasizes love before physics, knowing that the hard work that is truly meaningful and long lasting is a consequence of love.  But as Einstein reminds us, in doing such work we need each other and our collective efforts to complement each other.
