Everybody loves to focus on the things you must do to be a great leader. While there is nothing inherently wrong with this approach, it's often our weaknesses or things we don't know that end up hurting us the most.

Out of all the information out there in the world, there are things you know (<1%) and things you know you don't know (max 5%). An then there are things you don't know that you don't know (more than 95%.) Oftentimes, it's what you don't know that you don't know that crushes you and inhibits you and your team from reaching it's full potential.

Here are six of those things, I had to learn the hard way:

Being Unaware of the Power of Your Ego

Until recently, I didn't know how or even why I needed to overcome my ego. I now know ego is simply our own self-centered, self-serving, ambition. The desire to be more than, to be recognized for, or to be elevated above others. Ego is a conflict all leaders face, yet don't want talk about.

The problem with ego is it's "fake." People see it through it, they know it's ever-present, and either adjust their behavior to either take advantage of their leader's ego or disengage and just do what they are told. Ego leads to poor business and life decisions focused solely on the individual and their desires. It's the opposite of how the great Jackie Robinson thought about leadership when he said, "A life is not important except for the impact it has on other lives."

Lack of Self-Awareness

Gary Vaynerchuk the CEO of Vayner Media has been drilling the idea of the importance of self awareness for years. Vaynerchuck wrote: Self-awareness allows people to recognize what things they do best so they can then go hard on those aspects of their life. It also helps you accept your weaknesses.

Without being immensely self-aware as a leader, you almost stand no chance to have sustained success both in the relationships with people and growth of the company.

Forgetting the Principle of Quality

Callaway golf was founded by a man name Ely Callaway. For years when he ran the company he consistently talked about the need for the company to be "pleasingly different, demonstrably better." In the years after his retirement, the company struggled to remember the principle of qualify and it's products took a major turn for the worst.

It took CEO Chip Brewer to remember these words and the principle of quality to repair the company and get it back on track. So often we get so busy or worried about making a buck it's easy to forget quality.

Compromising Your Values

Values are simply person's principles or standards of behavior; one's judgment of what's important in life. Without question there will be times in your career where you will be tested to either forget your values or push them aside for short term gain. As Howard Behar said on the Follow My Lead Podcast, "at the end of the day values are all a company and a leader have, without them you are reduced to nothing."

Allowing Entitlement in the Culture

Brad Stevens the head coach of Boston Celtics who is widely considered one of the best coaches in the sport said, "We're building a culture of accountability, trust, and togetherness. Entitlement will not be tolerated."

Think about what Stevens is saying. His players make millions of dollars and it doesn't matter if you are his star player or the last guy on the bench entitlement will not enter the Celtics culture. If millionaires aren't going to allowed to be entitled nobody should.

Forgetting to Love Your People

When I say Love I don't mean any kind of HR violation. Instead we defined it, The Welder Leader Research as, "to contribute to someone's long term success and wellbeing." It's imperative you don't forget how important and the opportunity you have to help develop and contribute to others success and well being.
It reminds me of the great Harvey Firestone quote, "the growth and development of people is the highest calling of leadership."
