Final answer:
The statement is highlighting that realistic adaptation to challenges is effective.
Step-by-step explanation:
The statement is highlighting that realistic adaptation to challenges is effective.
The first part of the statement, where the pessimist complains about the wind, represents a negative and unproductive attitude towards challenges. The second part, where the optimist expects the wind to change, represents a hopeful but passive approach. However, the third part, where the realist adjusts the sails, highlights the importance of taking practical actions and making necessary adjustments to effectively overcome challenges.
This concept is supported by the quote by Maya Angelou, "If you don't like something, change it. If you can't change it, change your attitude." It emphasizes the need to adapt and have a positive attitude in situations where direct change is not possible.
