Help me with the text for a promotion

Hi, my name is Leonardo and I believe that The life begins only when we leave the comfort zone, so English is important to me because I want to have new experiences and to be a scientist. The most of the scientific articles are in English, because it is the most spoken language in the world. My dream is to help the world to discover the AIDS cure and to exchange experiences which would help me with my future as a scientist. I could tell you that this exchange is essential to my life but I think you already know this, the English changes lifes.
