In this quote, Enrique Iglesias is revealing a sense of nostalgia and longing for his past life. He indicates that his existing life, as a well-known artist, is not as fulfilling or satisfying as his previous "typical" life. This might recommend that fame and success have brought him more stress and pressure, triggering him to desire the simpleness and contentment of his past. It also highlights the concept that in some cases, the yard may not constantly be greener on the other side. Despite his success, Iglesias might have found more happiness in the simpleness of his previous life.
"Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday"
