Headache. Sleepy. Tired. Bored. All in one. I'm really need to focus. But how? Too many numbers in my head. Sometimes I don't know what I'm doing. I don't know the reason. Today and yesterday class sure killing me. I'm a dead.
Application in Mathematics give me headache. Totally headache. Suddenly, my hand write "HEADACHE" in a piece of paper. Nothing. Empty. Zero. Out of blue. Really need myself back. Even though the binary number is each but this is madness. Too complex.
