Neil Degrasse Tyson. (№ 425072)

When I first received and opened a book on mathematical analysis, it all from beginning to end consisted of formulas with deformed symbols, it contained half of the Greek alphabet. I didn't know what these letters were, how they were pronounced, or how to use them at all. Everything in one book! I then decided that I would never understand this. It looks so unattainable, but day after day you progress through the tutorial and learn more and more. One day you open the page and realize that this is a second-order derivative, as if the fog had suddenly cleared away. The lesson I learned is that hard work dispels ignorance. Since then I have been using it in my life. You should not judge your knowledge by how difficult or obvious it seems at first glance.
