What is a good sentence to use silently?

This is a tricky question! A sentence used silently can be anything you like, as long as it's a complete thought.

Here's the thing: "Good" is subjective. What makes a sentence "good" for silent use depends entirely on the context and the person thinking it.

Here are some examples of sentences you might use silently, each with different potential "goods":

* "I wish I could have that piece of cake." (Good for internal conflict and desire)

* "I wonder what's going on in their minds?" (Good for curiosity and analysis)

* "I can do this. I will succeed." (Good for motivation and self-affirmation)

* "That was a bad idea. I should have listened." (Good for reflection and self-critique)

Ultimately, the "goodness" of a sentence used silently is based on its effectiveness in your own mind. It might be helpful to think about what you want to achieve with that thought. Do you want to motivate yourself, calm yourself, or simply process something? The sentence you choose should reflect that goal.
