The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.

A secret is not something unrevealed, but something told privately, in a whisper.

The most difficult secret for a man to keep is his own opinion of himself.

One has to look out for engineers - they begin with sewing machines and end up with the atomic bomb.

I think most people would struggle to define their whole relationship with just one label - like: my girlfriend, boyfriend, brother, sister, confidantes, whatever - but in those moments, there's true joy in each other.

Anyone who starts piercing the bubble of happiness, get 'em out of your life.

Happiness, it's a small thing - just a very little thing.

If I can bring happiness to people all around the world, then I will try my best to do so.
