I am reading a book on study skills.

On a page it says

>Tend to coast along ‘in the middle’?
You have the opportunity to test out how well you
could do if you aim higher and adapt your strategy.
How far do you want to go? What would hold you
back from achieving more? Would you get more
satisfaction out of your studies if you brought **more**
to **them**?

My question: What is the last sentence mean? Especially the words **more** and **them**.

... brought more *satisfaction* or more other things?  
And what does the word *them* refer to?
