I love this quote from Randy Pausch’s book, The Last Lecture: “The brick walls [in life] are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something.”
If you haven’t heard of Randy Pausch check out his lecture on YouTube. He has a really inspiring story and presents gratitude for life in a different light.

What a great legacy Mr. Pausch left. So much truth rings through in that quote. He gave everyone lessons that were quite a gift in his last days.
