It's not so much about changing your mind, but rather more that as a learner of German, you have to do a bit more upfront thinking, and be more considerate of the thing you're talking about.

For example, "can you pass me the X" is straightforward in English, but requires a bit more thinking / planning in German where you have to consider "what gender is X, and what case is it in?".

Of course for a native speaker this is for the most part automatic. For someone learning though, it emphasises objects in a way that you didn't have to before. All of a sudden every item is distinct, has an additional attribute and must be used in a specific way.
