Yeah. I, I think an interesting thing with that is that like, is it even failure if you've learned from it and you've taken those lessons onto your next project or the next thing that you're working on? And it's like, that's not necessarily a failure. It's all just part of a long-term learning process.

No one has a 5.0 in real life. In fact, when you finish school, the whole notion of a GPA just goes away. When you're in school, every little mistake is a permanent crack in your windshield. But in the real world, if you're not swerving around and hitting the guard rails every now and then, you're not going fast enough. Your biggest risk isn't failing, it's getting too comfortable.

Working at the hospital, I found that my surgical skills were not as good as I expected. One time it took me two hours to do a surgical operation which could have been completed in 30 minutes by other surgeons.
