Am I using "that" too often? [duplicate]

Are there rules about using “that” to join two clauses?

"That" is a very difficult word for me. I keep feeling compelled to add it in just about any sentence in which I talk about an action or state something I believe/think.

I think that you're wrong.

Or

I hope that the company will get back to what they do best and come up with a proper keyboard next time.

Or

And don’t tell me that the price is justified.

Or

But I doubt that they have any programmers working on this.

All these constructions make sense without the "that", don't they? So then why do I feel this compulsion to add it?

Am I a "that" junkie? ::- D. Is there such a thing as a "that" junkie? ::- >.

No. Don't worry. It will pass. You're still apparently being thrilled by the freedom of adding or deleting complementizers ad libitum.

Generally, keeping that is useful in speech when one wants to be more formal, or to be more precise, or to appear to be more precise, or to provide an extra unstressed syllable to keep up the hypnotic iambic flow of a sales pitch.

Complementizer deletion is one of a number of shortenings that English uses, like contractions (don't, we'll), informal spellings of new contractions, (hafta, shouldna), Whiz-Deletion, Equi and Raising, etc. Like English (or better yet, Chinese) handwriting, such optional shortenings become matters of individual preference, as one learns useful ways to deploy them.

Executive summary: Develop your own style.
