Dear Self, Hey! I know you've been through a lot last semester. You've drunk countless cups of coffee and gone sleepless nights just to review for your exams. Do not think that all your efforts are not enough, it's just that you are studying for the most difficult subject of the engineering science department. I know that this semester, you'll make sure that you pass your exams and even aim for exemption in finals. You just have to put extra effort and your heart to whatever you study so you can truly understand the topic. Please never ever give up because it will be worth it in the end, okay?
