I really like the message of this piece. I think too many people are concerned with never making mistakes or being perfect, and the lesson you present at the end, of using mistakes as a source of wisdom and learning something from them is a lesson we should all take to heart when things don't quite go according to plan. We often learn more from our mistakes than we do from the things we do right!

From a technical standpoint, the piece felt a little unfocused. It starts with an anecdote about brushing your teeth with pain gel rather than toothpaste and missing a train (i.e., an unfortunate but relatively innocuous circumstance), and then specifically say that "making mistakes might be one of your strengths."

But the examples that come after (not telling your mother that you got in trouble at school and then losing your passport on an international trip) where the lessons learned are kind of very quickly summarized at the end as "don't blindside people" and "own your mistakes." While the overall point of the piece (embrace your mistakes and learn from them) is well-taken, it felt like a common throughline to these mistakes was missing, which led to the disjointed feeling where the theme of the piece is clear, but it's less clear how these three mistakes specifically tie together and why you chose them instead of other more thematically connective mistakes.

Overall, I think you're off to a good start here. You include a bit of humor to offset the serious tone of some of the concerns, and your writing style is casual and friendly. I think there's some room for refinement, but otherwise this was a very enjoyable read. Nice work!
