Positive expectation becomes powerful when supported by deliberate behavior.

Expecting a good outcome and behaving accordingly are two different things, and only the combination does anything. Deliberate behaviour is what turns an expectation into an influence on the world, since the world does not respond to attitudes. The behaviour is where the power actually is.

For each positive expectation you hold, identify the behaviour that would make it more likely and schedule it. Treat the expectation as a commitment rather than a forecast. That is the version that changes results.
