Macmillan Dictionary defines "to make of" as
to use chances and opportunities in order to be successful.
It also provides us two examples:
This job is whatever you make of it.
I want to make something of my new life here.
I have no idea about what this dictionary is explaining there.
However, it seems like I grasp the meaning of those two examples, with the second definition of "to make of" in the same dictionary :
to understand someone or the meaning of something in a particular way.
Could you explain to me what the first definition of to make of is and how does its meaning work in the given examples?
Or do you also gree those examples are placed in wrong position?
