It may sound too good to be true, but once you've seen the happiest people in your life who have nothing, you really start rethinking what the world, and society, tells us that we need to be happy.

The happiest people seem to be those who have no particular cause for being happy except that they are so.

The last few years have been my happiest. I'm happy in the years that most people are blue and sad and waiting to die. I don't feel that a bit. Smiling has a lot to do with it. You can just lift your spirits by smiling a little bit.

They think the banjo can only be happy, but that's not true.

You can't write masterpieces in your 80s and be happy too.

The happiest people in this world are those who have the most interesting thoughts.
