I am so self-conscious sometimes. Even now, I look for every excuse not to do my work. I get distracted and I don't see the time moving. That is my biggest issue. Sometimes, I don't see time moving. I permit myself the illusion that I'll make up this time later. But that couldn't be farther from the truth.

The point is not how long I sit at my desk or how late I stay up. It's how much learning actually happens. And there have been many times when I sat for hours at a time not learning a single thing. I've spent many hours looking to copy answers rather than actually solve and understand them. But these issues never actually solve themselves. In the end, it becomes harder either catching up, cramming, failing tests, losing sleep, stressing out, losing out on a life, etc....

Every single half hour of study has to be specifically oriented towards solving a specific problem or another. Each half hour's time - what sort of study will most likely specifically help me solve a problem on one of the exams? I must be ready to answer that question at all times.

What did you expect?
