Can someone explain the practical difference between technique and the tiny repair after a few failed attempts?

I had a disappointing first try, a surprisingly good second try, and then a third attempt that taught me humility. So, naturally, I now have opinions.

Context: I am not an expert, just someone trying to make Cooking feel less intimidating. I wrote down what worked, what felt awkward, and what I would do differently next time.

The detail that surprised me was how much a neighborhood park changed the outcome. Same plan, different setting, completely different energy.
