Is it worth it?

I decided to post this discussion to get everybody’s opinion and everyone can benefit from it.
I was wondering how hard is it today to make a GOOD living in the 3d/vfx industry?
Is it worth all the extreme effort you’ll put to it?
People say if you like than that’s what you need to do, on the other hand people say if it pays well and almost guaranteeing a pay check than that’s what you should do.
What you guys think, give your full opinion (it will help).
