The quote "the past is the past. Here we have a fresh beginning, but let that beginning start tomorrow" from John Boyne's book The Boy in the Striped Pyjamas emphasizes the importance of leaving behind previous mistakes or hardships and focusing on starting anew. It suggests patience and hope in allowing oneself time to heal and reset before moving forward. This idea encourages taking a measured approach to change, acknowledging that some things require a fresh perspective at the right moment.

The quote also highlights the significance of timing in personal growth and new beginnings. By postponing fresh starts until tomorrow, it reflects a realistic attitude towards change, recognizing that immediate solutions are not always possible or wise. It inspires readers to embrace hope and patience, understanding that the right time to begin anew is often just around the corner, if not tomorrow itself.
