Learning the hard way

I woke up one Monday morning and got late for school and when i got to my first class, math15, it was timely because they were just giving out the second preliminary exam's score. I got nervous because i knew that I just studied a day before the exam, because I got used studying a day before the exam during high school. When i got my score it lacked two points just to have a passing score, i got so disappointed to my self that Monday morning because I knew that I wasn't so good in my math subject yet I did not push myself to the limit while i was studying it. I now learned a lesson that i must give my heart in everything I do because in the end I would be the one to profit from it, but I learned it the hard way and it is through failing a major exam in math. I'm not a studious person because typically I am a lazy person, I am the type of person that needs to be pressured in order move or to do what I must do, but now I have learned that in whatever the authority over me has assigned me to do I would do it with my best, with my whole heart.
