The quote "If Muhammad won't come to the mountain, the mountain has to cancel all his plans and get on a plane," from Sophie Kinsella's book "Wedding Night," reflects the idea of taking action when faced with obstacles. It suggests that waiting for circumstances to change can be futile; instead, one should proactively seek solutions, even if it means going out of their way. This perspective encourages individuals to adapt and take initiative in their lives and relationships.

This phrase symbolizes the importance of personal agency and highlights the necessity of making sacrifices or adjustments to achieve one's goals. By using this metaphor, Kinsella emphasizes that sometimes it is essential to change one's approach or direction to foster connection and understanding, reminding readers of the importance of effort in love and commitment.
