If you have no idea who Ronda Rousey is at this point, congratulations, you're doing awesomely at living under a rock. To catch you up, Rousey is the UFC Women's Bantamweight Champion. She has a mixed martial arts record of 12-0 and her last four fights have lasted a total of 130 seconds, including her most recent one against Bethe Correia at UFC 190, ending after 34 seconds with a knockout.

In other words, she's five feet, seven inches, and 135 pounds of awesome.

This woman is a machine. She's trained in judo and has an Olympic Medal. She trains diligently with only the best and has laser-sharp focus. She doesn't get caught up in the drama of fighting, she just gets out there and lets her talent do the talking.

I believe that people have a lot to learn from Rousey.

Leading up to the fight, Correia said a lot of very insensitive things about Rousey. She said she hoped Rousey wouldn’t kill herself after losing the fight. This was very cruel to say to anyone, but especially it was a really horrible thing to say to Rousey, who lost her father to suicide.

Their staredown at the weigh-in prior to UFC 190 was an interesting one. The minute their eyes met, Correia immediately started shouting at Rousey. It was revealed later that she told Rousey not to cry after it was all over. Harsh.

Despite all this, Rousey kept her focus. Even when her opponent was screaming in her face, she stayed quiet and kept her focus. She wasn’t about to turn this into a shouting match. She hated that Correia had to make this whole fight personal, but she never backed down. Right up through the final seconds before the match, Correia had this “tough girl” look on her face, while Rousey looked prepared and ready to fight, but still calm and focused.

We all know what happened next.

The lesson here can be found in a quote I saw mentioned a lot the weekend of the fight: Confidence is silent, insecurity screams.

I’m sure Rousey has some insecurities. I’m sure it’s nerve-wracking to go into the octagon, even when you (and everyone around you) are 100 percent certain you’ll win. However, you would not have guessed that leading up to the fight. As I said earlier, she was focused and ready to fight. She was ready to let her actions and skills do the talking.

Correia, on the other hand, felt the need to constantly talk about Rousey, and to go into all of this with an attitude. To me, this was her biggest mistake. She talked a big game but couldn’t perform. Obviously, nobody wants to sit back and get beat, but her insecurities were showing. She attempted to portray a certain image leading up to the fight, while Rousey just focused on letting her skills shine through.

When you are searching for success, don’t talk a big game. Live a big game. It’s important to know your skills, strengths, and experience, but don’t constantly talk about them. Rather than telling everybody what a great athlete or worker or student you are, just stay focused on working hard. I promise, people do notice. They’re not always going to say something, but they do notice.

Stop comparing yourself to others. Stop trying to bring others down. We’re all guilty of talking about people, but if we all decided to focus on bettering ourselves, rather than bringing others down, we would accomplish so much. The world would be a much better place.

When you’re working your butt off to be better than you were before, you won’t even have time to worry about what others think or “proving” yourself.

It may seem a little silly that I’m using an MMA fight as a metaphor on competition with others and confidence. Obviously, fighting and sports will always have a little trash talk. Life will always have a little trash talk. But don’t make the mistake that Correia did: letting it consume you. Correia was so worried about proving that she’s better than Rousey when she should have been focused on what she’s going to do in the octagon.

Save your energy for whatever your octagon might be. Don’t worry about others and how you look in comparison, or how you look or seem when you do something. You will come out a success story either way, because you are better than who you were yesterday.
