When I first arrived in the US, we lived in a hotel and hardly had enough money to buy food. I did not understand the language and we had to walk in the 100° degree summer. While most would hear that story and feel sorry, I think back to that time and do not remember sadness or despair. Instead all me and my family saw was hope, something that we had not felt in a long time. The past eight years in Mexico had been very tough. My mother was a pediatrician charging 10 pesos -less than a dollar- per consult and my dad had been unemployed on and off for the past few years. After only a couple of months our dreams here in the US began to come true. My dad got himself a job and we soon moved into an apartment. I soon began to see that not knowing English was an adventure instead of a disadvantage. I started reading kindergarten books in English and in less than a year I could already hold a fluent conversation. Soon after that, I was moved to the gifted class and I was informed of the endless possibilities that my future held if I just kept working hard. As I reflect on my life now, I can honestly say that I have everything I have ever wanted. Even if there is ups and downs and there is always obstacles trying to defeat us, I know hundreds of people who would give anything to someday have a tenth of what we have. Not only those across the border, but simply those 15 minutes away from where I live. Immigrating from a different culture and country has given me the opportunity to see things from a different perspective. I realize all that has been offered to me and that there is many more roads to be explored. There is nothing but gratefulness from me for all that God has granted me and I will make sure that I continue to use my talents and time to give back as much as I can. I want to go back to where I came from and go to many other places that I know are in desperate need for even the simplest of things. I will use my love for education to obtain a Dental profession. This will soon enable me to give peace to children and others who can not even afford a simple tooth extraction and have to live with the pain for weeks. Not only that, but I will also be able to use my background to expand the horizon of other joining the dental profession. Hopefully, that will help them realize all that they can do with their talents or at least better understand a wider range of patients. My Hispanic heritage has made it clear to me that every ounce of sweat brings with it a pound of success and that the only way we can receive happiness and is by giving.
