For this post, describe one mistake you have made in your life. The mistake could be significant or minor; it's up to you.
For example, I failed my first driving test: on the three-point turn, I backed into the curb, and the DMV evaluator said, "That's it. You've just failed the test; you might as well turn around and go back now." In retrospect, it's true that I wasn't a very good driver, but the three-point turns were the least of my driving deficiencies . . . Hopefully, I'm better now.
