Develop credibility, humility, and a love of learning using a simple phrase

In the modern economy, expertise, skills and knowledge are some of the best measures of your competence. Many of us are afraid to admit whenever there's something we don't know. Despite that, one of the most important skills we need in the age of information is the ability to say "I don't know" both to ourselves and to others.

First, being able to admit that you don't know something forces you to stay humble. Being honest with yourself and others by saying "I don't know" means that you don't overstate your area(s) of expertise. This prevents you from receiving false recognition, which prevents arrogance and over-inflation of the ego.

Being able to say "I don't know" also keeps you curious and ready to learn. I'm not sure how most people are, but personally, if I'm asked a question and I don't know the answer, it bothers me. I want to find out the answer and look it up. That kind of behaviour develops curiosity and a love for learning new things. All because I admitted to myself and whoever is asking me a question that I don't know the answer.

Most importantly, in the long term, saying "I don't know" will keep you from losing credibility. There's always pressure to be a "subject matter expert", as well as the pressure to provide immediate answers without knowing what you're talking about. What will likely happen in this situation is that you'll give inaccurate information.  The person who receives that inaccurate information will make decisions, act on that information, and suffer the consequences.  When they do, you'll be blamed for their failure and be thought of as unreliable or worse, a liar.

Yes, it's important to be knowledgeable and skilled.  It's important to be able to answer questions about your field of expertise.  This is what competence in any field looks like. However, no matter how competent you are, there will always be something that you won't know. And that's all right. We're now in a world where almost all of human knowledge can be accessed almost instantaneously using a device in your pocket. You're better off saying "I don't know. I'll give you an answer as soon as I find out."

Feeling Insecure? Use the 8 Mile Method

A lot of problems, conflict, resentment and aggressive behaviour usually come from our own insecurities. We're all insecure about something because we're all flawed in one way or another as human beings.

Many of us feel afraid and insecure because we're afraid that at some point, those flaws of ours will be exposed and used against us. Some will use them to make us feel bad about ourselves. Others who are more Machiavellian will use those flaws and insecurities to manipulate us to their advantage.

So how do we avoid our insecurities getting the best of us? Use the "8 Mile" method.

In the movie 8 Mile, Eminem's character had to go through several rap battles where freestyle rappers try to get the best of their opponents by insulting them to a beat, as creatively as possible.  *Spoiler alert*:  At the end of the movie Eminem's character, at the final rap battle, decides to point out all of his own flaws in public. Basically, he dissed himself before his opponent could do it.  By doing that he took away any ammunition that his opponent could use against him.

The first step is to take an honest look at ourselves in both the literal and proverbial mirrors. That honest look will allow us to identify our flaws. This not only gives us the choice of doing something to get rid of those flaws and improve ourselves. It also allows us to accept the fact that we have said flaws and take ownership of them.

Once we accept that we have our flaws and we start owning them, (or better yet, we start working on eliminating those flaws), these insecurities will slowly start disappearing.
