To Be Successful Stay Far Away From These 7 Types of Toxic People You need a network of talented people, not toxic personalities who undermine you.

Surrounding yourself with prospective mentors is an excellent way to build lifelong success. When Steve Jobs founded Apple, he learned from colleagues like Steve Wozniak about what it took to build computer hardware. And he learned from early investors like Mike Markkula about what it took to build a successful company and market a product. Now imagine if Jobs had surrounded himself with toxic personalities instead. It is likely that he would not have been able to create a company that is on course to be valued at $1 trillion.

If you interact with people who demonstrate questionable behavior, you're more likely to model that behavior yourself or to become stressed as a result. At the very least, you will be missing out on the opportunity to network with more successful and inspiring individuals.

This article will review seven personality types that should be eliminated from your life in order to build your most successful self. Once these people are gone, you can work on building a network of people who influence you positively.

1. Micromanagers.

According to a report by NPR, micromanagement is one of the biggest factors associated with employee dissatisfaction, lowered motivation and lack of professional creativity. To be successful, you must learn to solve problems independently. Micromanaging can make it difficult to develop these skills.

2. Short-term thinkers.

If you surround yourself with short-term thinkers, it will be difficult to know if an idea is destined for long-term success. Those who are narrow-minded may be more likely to dismiss one of your ideas because it will take time to develop into a meaningful success.

Take the creation of Airbnb as an example. The company was founded in 2008. At the time the "sharing economy" did not exist, and hotel chains like Starwood and Hilton dominated the lodging market. A short-term thinker would have criticized an idea like Airbnb.

In order for the company to be successful, Airbnb would need to change people's attitudes and expectations about travel. They would need to encourage people to be comfortable staying with strangers, and they would need to find ways to mitigate possible liability should something tragic happen during a customer's stay.

Well-respected venture capitalists decided to pass on Airbnb because of these short-term concerns. The Airbnb founders were only able to find success once they connected with people who were comfortable thinking long term.

3. Pessimists

Pessimism is not always a bad trait; at times it can help entrepreneurs to recognize certain pitfalls that might otherwise be overlooked. However, a steady diet of pessimism is toxic when it comes to taking big professional risks.

As David Armor, an assistant professor of psychology at Yale University, says, "An entrepreneur starting up a company, for example, might drive himself to work 18-hour days for months and even years because he optimistically believes that there will be a big payoff for him at the end." Conversely, a pessimistic attitude would make it difficult to tolerate such a prolonged stressful situation.

For those interested in taking on stressful professional situations, pessimistic people should be avoided in most cases.

4. Selfish people

Relationships that contribute to success are mutually beneficial. This dynamic cannot exist when dealing with selfish people. As a result, it is best to eliminate selfish people from your life in order to make room for more giving relationships.

A recent study found that a job applicant who is referred by an existing employee is 15 times more likely to be hired than someone who applies via a job board. If you befriend a selfish person, you probably can't rely on them to introduce you to new career opportunities. However, forming connections with someone who is altruistic could give you a professional leg up.

5. Risk-averse personalities

Business success is about making informed decisions by weighing risks and rewards. If you are surrounded by people who over-index on possible risks while ignoring the possible rewards, it will be challenging to identify good business opportunities.

Take Amazon as an example. In 2014 Amazon launched a smartphone called the Fire Phone. In the end, the phone was not successful. Following the unsuccessful launch of the Fire Phone, risk-averse people might have avoided developing another piece of computer hardware.

But instead, Amazon correctly assessed the opportunity for an in-home smart speaker, and launched the Amazon Echo just one year later. Today, Echo has 75 percent of the smart-speaker market in the United States.

6. Unmotivated individuals

People who lack motivation or work ethic set a bad example for those interested in working diligently to become a professional success. There is no worse colleague than someone who simply does the bare minimum to get by.

Rather than associate yourself with people who cut corners or avoid hard work, try to surround yourself with people who are motivated to succeed. Collaborating with people who have a healthy drive for success can instill an extra dose of motivation in you.

7. Spendthrifts.

Financial responsibility is a critically important quality to develop if you want to become successful. Warren Buffet is perhaps the supreme example of a financially responsible and successful person.

Buffet is the third wealthiest person in the world, worth nearly $80 billion. But despite his professional success, Buffet does not spend his money on flashy cars or large homes. In fact, Buffet still lives in the modest home in Omaha, Nebraska, that he purchased in 1958.

Those who associate with spendthrifts may be more motivated to make irresponsible financial decisions in order to fit in. At the very least, it will be harder to associate with people who make good financial choices, as these personalities are frequently diametrically opposed.

Conclusion

Business is all about who you know. From landing a new job to launching a new company, your network will enable or prevent future professional success. When developing a network of talented people, it is best to avoid toxic personalities who could set a bad example or demotivate you.

Be sure to avoid people who are micromanagers and short-term thinkers, as they can make it difficult to think autonomously. Risk-averse individuals or pessimists may cause you to think twice about great business ideas, and spendthrifts or selfish people may hamper your ability to grow. Last but not least, stay away from unmotivated individuals, as your success is dependent on your willingness to work diligently in order to succeed.
