Being a good student

This is too much
I begin to be very busy.
Writing paper for Mr.Saunir
Reading novel, listing difficult words, and searching about 20 articles for Mr. Jufri
Preparing presentation material every meeting and doing each number of exercises in the book for Mrs. Hermawati Syarif
and the others assignment

I have tried scheduling my times, but it is still not enough
I lecture in morning, do assignment in the night,
and sleep 4 hours before I should wake up in the following morning

It is difficult to be a good student
Actually, I can ignore some of assignments but I won't.
And I have to face those difficulties
