Son of Mars

I'm being trained 7h/day at company. Beside this course, I have to study and practice Java for preparing SJCP exam on next Saturday. This training rate is so hard, more than 9h/day . So that, after all I just wanna sleep only. Maybe, there is a solution for this case, I'd be Nobita and try to ask Doremon for his help, something like "knowledge bread" would be suitable . Even though, it cannot be true, but it's so fun when I think of it.
