Jeff Keller opens with the premise that attitude is a deliberate choice available in every circumstance, not simply an automatic reaction to what happens to you.

The core distinction he draws:

• Circumstances are often outside your control; your interpretation of them isn't
• The same event can be framed as catastrophe or opportunity depending on chosen attitude
• Most people never examine this choice consciously — attitude runs on autopilot, defaulting to habitual patterns

Keller's opening challenge: start treating attitude as a decision you make repeatedly throughout the day, not a fixed trait you either have or lack.
