12 Business Mistakes You Absolutely Shouldn't Make

As entrepreneurs, we are told that it is always OK to make mistakes, but are there some mistakes that you should never make because they will destroy you and your business?

The following answers are provided by the Young Entrepreneur Council (YEC) is an invite-only organization comprised of the world's most promising young entrepreneurs. In partnership with Citi, YEC recently launched StartupCollective, a free virtual mentorship program that helps millions of entrepreneurs start and grow businesses.

A. Not Following the Data

2014-01-21-Mattehrlichman.jpgMistakes are great as long as you are learning from them. The worst thing an entrepreneur can do is make a mistake and not follow the hard data that is produced from the results. It's using lean startup methodologies -- always test and use the data to guide your future decisions.

A. Burning Bridges

2014-01-21-BrennanWhite.pngPeople often forget that you will have a life after your business. Your goals should be long term and as such, you should treat each person you meet with respect. You will very likely remain in that person's orbit (even if it feels like you won't at the time), and negative effects of a burned bridge will continually impact your future.

A. Lying

2014-01-21-CharlesGaudet.jpgYou can make more money by being honest and trustworthy than you can with shady and dishonest business practices. Once you have a reputation of stretching the truth, you're toast. Customers value transparency and integrity, even if it means owning up to a mistake and vowing to make it right for them.

A. Ignoring Market Info

2014-01-21-JTAllen.pngStart-ups are created to address problems in the market. But, as you build the solution to the initial problem, you learn more and more about the market and the dynamics that cause the problem or you discover a different problem. Don't be afraid of what you learn. Pivot your solution to address new information. Solve a problem in the marketplace that people will pay for, and the rest is easy.

A. Making It Personal With Your Team

2014-01-21-AaronSchwartz.jpgThe greatest asset any startup has is its team. You work closely on a daily basis toward a shared goal; without 100 percent alignment, you probably won't get there. On the journey, tensions will often rise. The one mistake you must avoid is making a disagreement personal. The discussion always has to anchor around what's best for the business; hurting someone personally will kill trust.

A. Not Vesting Your Equity Over Time

2014-01-21-DougBend.jpgIt is extremely difficult to find the right co-founders for your business. You need to have a similar work ethic and timeline for the investment, your chemistry has to match, and you have to make sound decisions for the company. Instead of getting all of your shares at once, consider vesting your equity over time so you have a fair solution if these factors do not line up, which is often the case.

A. Forgetting Those Who've Helped You

2014-01-23-BobbyGrajewski.jpgAlthough it may not necessarily destroy you and your business, it is a good practice to treat everyone with respect and kindness. Never forget the people who helped you along the way.

A. Avoiding Accountability

2014-01-21-CharlesBogoian.jpgOne mistake that will doom an entrepreneur is shirking accountability in the aftermath. The partners and customers who will be of value to your business in the long term will appreciate your acceptance of the responsibility and may even gain respect for showing character in a difficult situation. Conversely, reassigning blame shows a lack of confidence in your business and in yourself.

A. Saying Something You Could Regret

2014-01-23-JonathanMead.jpgIt doesn't matter how angry you are or how stupid a customer or client seems. Never say anything you wouldn't want published in a major media outlet.
- Jonathan Mead, Playbook

A. Having a Bad Credit Score

2014-01-23-BrendonSchenecker.jpgKeep an eye on your debt, and check your credit score regularly. Most mistakes are recoverable, but bad credit can last a long time. It is much easier to get a bad credit score than recover. Capital can drive a business to success, but without it? Well, let's just try and avoid that.

A. Being Arrogant

2014-01-23-PhilDumontet.pngI think the golden sin -- the only truly unrecoverable mistake -- is having unjustified arrogance. If multiple things or people are independently telling you that you're wrong, then you're a fool for not pushing your ego aside and doing something to change it.
- Phil Dumontet, DASHED

A. Letting Clients Bully You
