When I look back on all these worries I remember the story of the old man who said on his deathbed that he had a lot of trouble in his life, most of which never happened.

Worry is interest paid on trouble before it falls due.

Rule number one is, don't sweat the small stuff. Rule number two is, it's all small stuff.

How much pain have cost us the evils which never happened.

A man gets on a train with his little boy, and gives the conductor only one ticket. 'How old's your kid?' the conductor says, and the father says, 'He's four years old.' 'He looks at least twelve to me,' says the conductor. And the father says, 'Can I help it if he worries?'

I highly recommend worrying. It is much more effective than dieting.

It ain't no use putting up your umbrella till it rains.

Worrying is the most natural and spontaneous of all human functions. It is time to acknowledge this, perhaps even to learn to do it better.

A person must try to worry about things that aren't important so he won't worry too much about things that are.

Niche worrying is a means of conveniently organizing one's paranoia. It's concentrating on a specific fear or phobia at an appropriate time, like focusing on getting legionnaires' disease from inhaling steam containing Legionella pneumophilia bacteria while taking a shower at the gym.
