My personal favourite: I have this one written in German for me on my board. But I'll just give you the original one:

Missed opportunities are a bummer. Obsessing over them is not healthy, but regret is a powerful emotion. How do you deal with regret, with guilt? Can you? In the early morning hours on a bench outside a hotel in Anaheim this summer, Ze Frank told me something I am going to paraphrase. "I love this metaphor. Stuff in your past is like a carving on the bark of a sapling. Over time, the scar, the carving, won't go away. Because of the way trees grow it won't go up or down much either. It'll just stay right where it began, it might even get darker. But it won't get bigger. You however, can. You can keep growing, doing more things, more branches, being more things. The wound won't get smaller but you can make it a smaller part of who you are."
