This is an interview with an idol star. What does this "it" refer to? "this" seems to refer to "a lot of pressure", and does "it" refer to the same thing or a general meaning?
62)KM: What was the hardest part of your training?
JP: I was just 16, but I had to give up a normal teenager's life. There was a lot of pressure, both mental and physical. I asked myself many times. "Is this worth it?"
KM: And was it worth it?
JP:(laughs) It was for me! But before you start, you need to make sure it's what you really want...
not a teacher
I'm not so sure, Mike. "Is this worth it?" is of the same form as "Is this job worth all the hassles involved?", "Is this view worth the time it takes to get here?".
In other words, "this" is the thing that is gained and "it" is the thing to be endured.
So in this case I think it means: ""Is this (being a star) worth it (the pressure)?"
I agree with JMurray. Is this (the outcome) worth it (the hassle)?
