Is it hard to become a radiologist?

How hard is nursing school exactly? Is it in high demand all over?

I just graduated high school and I am ready to begin school but don’t know if I should go for nursing because I am afraid it will be too hard..My dad is an Registered Nurse so maybe that’s an advantage?

What about radiology? Is it in high demand?

Or would it be smarter to go to the other side of the spectrum and do something with technology
