That I visited many of the places that I one dreamed I would. The Great Wall of China stands out. Just never thought it would be possible to afford to travel abroad let alone go half way across the world. The day I walked on it, I was seeing it through the eyes of my childhood. All those lonely days spent in the bedroom heading history and geography books dreaming of it. No other historic sight has ever compared for me, just magical.
Also that I stopped wetting the bed.
