Whether you intend to or not, if you allow yourself to use words and phrases that convey doubt, insecurity, and a lack of true belief in what you’re saying, you’ll eventually lose faith. Not only does this effect your own mental well-being, but the people you’re communicating with will read into your word choice and pick up on your sentiment & body language.

Here are the seven words you’ll need to eliminate from your vocabulary if you want to be successful.

1. “Might”

This one is my all-time least favorite word. Anytime I catch myself using it in conversation, I force myself to first think about why I would be unsure about what I’m promising or expounding about—especially in a business situation. “Might” is most commonly used to highlight something that may be a possibility. In business, you need to be very sure of yourself and the decisions you’re making. If you’re not, others will pick up on your insecurity and have a difficult time believing in you.

2. “Usually”

In a business context, “usually” is another word that expresses doubt about a situation or set of circumstances. Its lack of definitive nature tells the person you’re conversing with, that they shouldn’t confidently believe in an outcome that happens only most of the time.

3. “Should”

Similar to “might” and “usually,” the word, “should” also conveys a general lack of confidence and certainty in the result you’re really just hoping for, rather than taking the necessary time and preparations to make sure you execute flawlessly.

4. “Won’t”

Using this word is one of the quickest ways to put someone on the defensive. Instead of using a less personal word to decline participation in an activity, the word, “won’t” has an air of stubborn rejection to it.

5. “Likely”

If you’re using the word, “likely” in a business setting, you’re really doing nothing more than making a prediction. Not only are you clearly not confident in the results or outcome you’re talking about, but you’re making clear your lack of personal knowledge on the matter.

6. “If Only”

Nothing says that you’re living in a dream world more than talking about business situations with the ever-hopeful, “if only.” Here, you’re actively stating that you don’t have control over what’s happening, and it gives the impression that you’re just grasping at the hope of some sort of divine intervention. Quit dreaming of the things you could do with all the resources in the world, and instead, focus on making your dream come true with the tools you do have.

7. “Really”

In a business sense, the word “really” is a very casual expression that attempts to place extra emphasis and importance on a particular outcome, without really quantifying what exactly that extra emphasis is. The word rarely adds any real value to your conversations.
