My dear,

A pessimist complains to no avail. The optimist is cheerful with nothing backing up their happiness. And the realist takes action. The realist puts the responsibility of being happy on themselves. For who is more responsible for their own happiness than themselves?

The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.

Learn to be realistic.

Falsely yours,
William Arthur Ward
