In Cecelia Ahern's book "If You Could See Me Now," the author emphasizes the importance of recognizing the choices available to us and appreciating what we possess. Many people tend to overlook their options and magnify their desires, losing sight of the value in their current situation. This shift in focus can lead to a more fulfilling life, as it encourages gratitude rather than dissatisfaction.

Ahern also distinguishes between positive thinking and mere wishing. She argues that wishing and dreaming should be seen as acts of hope and belief rather than expressions of discontent. Instead of complaining about what is lacking, individuals should engage in constructive thinking that uplifts and motivates. This positive mindset promotes resilience and a deeper appreciation for life's blessings.
