Write a notebook entry as it's easier to find people who will correct your sentences. Here are my suggestions.
My goal for the new semester is to read more books. I made up my mind getting to know much more to achieve my dream someday. (This is not clear - Did you mean - I made up my mind that knowing a lot more, will utlimately achieve my dream).
That's the way that I need to improve. To read more books, I'm going to the library often. Firstly, I will be able to know and learn about new things, Secondly, I will acces e-books. By doing so, I can have more time to read and e-books are easy to carry.
In addition, I can save millions of trees by using e-books.
I believe going to the library often and accessing e-books will help me reach my goal.
