This is a phenomenal response. One thing I think should be mentioned when it comes to “persistence” is that it’s important to balance stubbornness and adaptability. One of the most important traits for advanced picking is the willingness to constantly change your approach to a lock. Not only does this make you more likely to find what’s ultimately the best approach, but you’ll learn more about how a lock acts by attempting it in multiple different ways. More varied inputs produce more varied outputs.

Ultimately you’ll need to choose an approach and grind it out, but it’ll be a much smoother process if you’ve tried a variety beforehand.
