My first hackathon when I was in my university. I never used to work on any side projects apart from assignments and academic projects. I was so shocked when I saw that people were so dedicated in developing a working product in a weekend sacrificing sleep and food. I got so depressed that I wasn't doing anything and people around me were doing so much!!!!! That's when I was motivated to learn more, do more, work more. After this, I never missed a single hackathon while I was studying :) I'm so much better at what I do now because of hackathons.
