In highschool there was this guy who used to study a lot. Everybody said he was studying too much, and that he needed to study that much because he wasn't that smart. Finally he graduated with one of the best averages in our class. Then he got into the best engineering school in Chile, and I remember thinking that maybe he wouldn't be able to make it, or that he wouldn't have such good grades. Well, I was wrong. He graduated from engineering with a great average.
Now I don't know where this guy is working or what he's doing, but I have no doubt he will achieve whatever he sets himself to accomplish. For me, he is an incredible example of how will and discipline got him to achieve the things he wanted.
2 other stories about this guy:
1. Until he was around 12 he was fat. Then one day, after summer vacation he came back to school thin. He stayed like that at least until he finished engineering.
2. Junior year in highschool he had the best average in the advanced math class. There was a math competition and he was not chosen to go. When he asked the teacher about this, the teacher said: "for this competition we need talent, not effort"
