EDUCATION IS A PROCESS AND NOT A PROFITABLE BUSINESS! THAT IS WHY IT REQUIRES INVESTMENTS WHICH I CURRENTLY CAN HARDLY AFFORD. SPECIFICALLY, IT DEAL WITH STIPULATING THE ENGLISH TEXTBOOK OF MY OWN TO THE STUDENTS. I INTEND TO PRINT AS MANY TEXTBOOK AS I CAN. HOPE THAT YOU CAN CONTRIBUTE TO IT, TOO! 

THANKS IN ADVANCE!
