Growing up, I discovered that l could predict the future. One of my first predictions was in high school: I declared that my entire class would pass the mathematics exam, and, sure enough, we did. Of course, this was only after I used nearly all of my free time to make sure my classmates understood the calculations and formulas.
I learned that you can predict the future if you do the hard work.
I also learned that I really love numbers; I love how definite they are, how one plus one is always two and how two plus two adds up to four. I think I may have inherited this love of numbers from my father.
