So, you have a great idea. Awesome! But if you want to make that idea into reality, that’s not all you need to succeed. Whether you’re going to make it or not doesn’t only depend on your wits and good ideas. In fact, that’s only the tip of the iceberg. The other 90% is your state of mind, your resolve, and your communication with others. Successful people know this—and that’s why you’ll never hear them say any of these 15 phrases.

1. “That’s impossible.”

The first thing an unsuccessful person says is “that’s impossible.” They put limitations on themselves right from the start by creating their own imaginary roadblocks. However, successful people know that anything is possible if they put their minds to it, with enough determination and effort. Sometimes, it just takes a new perspective or creative thinking to find a way to make the impossible possible.

2. “I can do it all by myself.”

This is a common misconception. Yes, you can do anything you set your mind to, but that doesn’t mean you have to do it alone. Teamwork is essential with certain tasks, or sometimes, you just need the support of others to help you achieve. Only unsuccessful people think they can do everything all by themselves 100% of the time. Successful people know the importance of delegating tasks and surrounding themselves with competent and supportive people.

3. “That won’t happen for me.”

This phrase rationalizes letting go of your dreams and goals. One person will get the job or opportunity; why can’t it be you? Successful people are not afraid of competition or challenges. Instead, they use them as an opportunity to push themselves harder and prove that they are capable of achieving their goals.

4. “Jane is so ahead of me in life.”

Comparison can be a motivation killer. Successful people understand that everyone is on their own path and journey. They don’t compare themselves to others as a distorted sense of self-worth. Instead, they use those ahead of them as inspiration and motivation to keep pushing themselves to achieve their own goals.

5. “I have a problem with that.”

Of course, challenges will come along the way, but it’s important to approach them rationally and calmly. Successful people understand the importance of keeping their emotions in check when things do not go as planned. They look for solutions to problems rather than making the problems bigger than they are.

6. “Don’t forget the details.”

It’s not uncommon for people to become obsessed with the details when a new concept is introduced. They want everything to be perfect right from the start. Successful people know it’s not the case; details are important, but they’ll come in time. They focus on the bigger picture first and then worry about smaller details as they work towards accomplishing their goals.

7. “I like my own idea.”

Successful people understand the importance of being open to suggestions and feedback. They acknowledge that they don’t know everything and that others can bring new perspective and ways of doing things. They welcome constructive criticism and use it as a way to improve their ideas.

8. “I don’t need your input.”

Only unsuccessful people claim they don’t need advice and constructive criticism. Successful people understand that they aren’t perfect and value the opinions of others. They consider all feedback and take advice from people they trust. They constantly look for ways to improve themselves and their ideas.

9. “I already know that.”

This statement hurts the morale of the team rather than being constructive. Successful people never dismiss or discourage others from offering advice, even if they think they already know what’s being said. They recognize the importance of being open-minded and respectful towards the opinions of others.

10. “Let me check my schedule.”

Successful people know that time is valuable and that they need to be careful with how they manage it. However, saying this phrase can make someone feel as though they’re unimportant, and you don’t value their time. A better response would be to show enthusiasm and interest in what someone is proposing and offer to figure out the best time that works for both parties.

11. “You must be wrong about that.”

This phrase dismisses someone’s point of view without even considering the issue. Successful people are respectful of others and acknowledge that alternative perspectives can be beneficial. They take time to understand and research issues that are brought to their attention.

12. “I can’t.”

Successful people never dismiss possibilities and opportunities by saying “I can’t.” They know that the phrase is limiting themselves and that a can-do attitude is necessary to achieve success. Successful people are not afraid of their failures; they see them as opportunities to learn and grow.

13. “Nobody can see my work until it’s finished.”

Successful people know that collaborations and feedback are essential to achieving success. They understand that new perspective can help to find faults in their work and that these faults can be corrected before the final product. Successful people are open-minded and invite people they trust to offer their opinions in developing their ideas.

14. “There’s no time for me to relax.”

Successful people know the importance of taking breaks and winding down. They understand that they can’t go full speed forever and that it’s essential to allow yourself time to decompress from your work. Success is not just about working hard; it’s also about balancing your work and your personal life.

15. “It’s not fair.”

Complaining that life is unfair is not only unproductive but also unhealthy. Successful people acknowledge that things don’t always work out the way they planned, but they move on and keep trying. They do not blame external factors or circumstances for their setbacks; they take responsibility and continue working towards their goals.

In conclusion, successful people strive to avoid these phrases as they know they inhibit success. These phrases are commonly used by unsuccessful people and often hold them back from reaching their full potential. Understanding how to communicate and approach challenges is critical to achieving success, and that includes avoiding these phrases.
