When was the last time you worked incredibly hard?

I had an experience getting deep into algorithms. Last year, I got to know the importance of the algorithm as a computer science student. Learning it was a way for me to improve my creative and logical thinking, so I decided to study it properly. At the beginning, I struggled to understand difficult ones, as well as finding the right codes that were the solutions to problems that I had to solve. I took a lot of time and effort doing it, but, finally I felt like I learned a lot. I also could find what I like and improve my future prospects. I'm really thankful for it. I think everyone has their own talent. You've got to find something that you can put your mind to.
