It can be hard to give yourself a break. But I have the belief that "The first time something goes wrong, right, or upside down, is simply education." Some types of education come at a higher cost than it may at other times. The only time I start to wonder about people is when they make the same mistake more than 3 times, while they wonder why it didn't work this time.
At any rate I'm so sorry about the duckling.
