What does testing mindset mean to you? What's your tester mindset?

Here is another example of tester mindset illustrated by an example

I have found often the mindset between someone who is a developer to be different from a tester.
They get asked to build something, and think about how it should be written to make it happen.
With testers, we get told something is wanting to be built, and we turn it around and upside down. We ask “What if…?”, and either want the answer proven, or find out there isn’t an answer which means it will need to be answered.
