Part of us believes the new car is better because it lasts longer. But, in fact, that's the worst thing about the new car. It will stay around to disappoint you, whereas a trip to Europe is over. It evaporates. It has the good sense to go away, and you are left with nothing but a wonderful memory.

We don't believe other people's experiences can tell us all that much about our own. I think this is an illusion of uniqueness.

I think good things are happening to me and will continue. I am not optimistic about the rest of the species, but I'm so blessed, it's almost scary. I'm sorry to disappoint you, but I have a wildly sunny disposition. I love to laugh.

No one likes to be criticized, of course, but if the things we successfully strive for do not make our future selves happy, or if the things we unsuccessfully avoid do, then it seems reasonable (if somewhat ungracious) for them to cast a disparaging glance backward and wonder what the hell we were thinking.

Natural life, lived naturally as it is lived in the countryside, has none of that progress which is the base of happiness. Men and women in rural communities can be compared to a spring that rises out of a rock and spreads in irregular ever-widening circles. But the general principle is static.

My transactions are above board: I do not have money deposited in other accounts and have transparently declared all assets. My real wealth is, however, my experience as cofounder of Infosys and as Aadhar Chairman, which gave away 60,000 crore identity cards to people of India as promised.

As someone who cares about human rights, I am deeply dismayed to learn that Mr. McCain's charity has accepted money from Saudi Arabia. Their track record of oppressing women, gays, Christians, and political opponents is notoriously horrific.

I firmly believe caretaking the soul is incredibly important for happiness.
