Barbie just came out with a new ad.Take a moment and watch it.

First of all, isn't it too stinking cute? I immediately fell in love with these little girls and I hope you did too. When I was their age, I wasn't sure what I wanted to do with my life. According to my mom, I wanted to be a "Mexican hat dancer" (please don't take offense to it, I believed them to be the coolest group of people in the world). I am pretty sure I didn't even know what veterinarian, professor or soccer coach careers entailed.

My first thought was that these girls couldn't be more than 6. How could they possibly know what they wanted to do with their life at such a young age? How could they be so determined?

My next thought was, why were others judging them when they came into the room? Why did others laugh? Did they not think they could do it? In all honesty, a 6-year-old cannot teach a class full of college students, give an accurate assessment of a sick animal, or coach a world-winning soccer team. But the minute the students, patients or soccer players gave a sign of doubt, they could have killed their dream.

Regardless, the little girls kept on pushing. They continued with their feat. They didn't care what others thought about their choices. When I noticed this, I then realized they were brilliant. They were smart enough to not let society stop them. They were smart enough to block all the negativity out and push forward with their lives. Why couldn't I do that at their age? Why, sometimes, can I still not do that? Shoot, if a 6-year-old girl can do it, a 19-year-old girl should be able to do it.

Don't worry, I no longer want to be a "Mexican hat dancer" but my mind constantly races back and forth, thinking about my life goals. I have so many interests and ideas about life and I am trying to narrow it down. My current desire is to be a pediatric surgeon with a Spanish background. Sometimes when I tell others my goals, they shoot me down. They say, "Why would you want to go to school for so long and have all that debt to pay back?" or, "Are you sure that is really worth all the stress of a double major?" This leads me to think I can't do it; I am not strong enough or I cannot do what I want.

Sometimes we humans feel like we can never be good enough. We can never work hard enough, study hard enough, or be kind enough. We have to fight for approval. But I am here to tell us that everything we do is enough. It shouldn't matter what others think of us. As long as we are confident in ourselves and our goals, that is all that should matter. We should never feel like we can't dream or aspire to be something so out of our comfort zones. Those little girls should feel like they can be whoever they want, even when they aren't playing with Barbies.

I should never feel like I can't strive to be a pediatric surgeon. So I have decided to not let that feeling ever enter my mind. It's up to us to change the future. It's up to those 6-year-old girls. Don't ever let anyone change your mind. Be the person you want to be. You can do anything, as long as you put your mind to it. I believe in you, so believe in yourself.
