Is a high school counselor a good job

A potential goal in mind is becoming a high school counselor. I was wondering if this a good career? How long does it take to become one? What major do I need to take? I’m transferring to a university with a psychology major from my community college, and one of my main goals is to go into a career relating to psychology. Could I become a high school counselor if I major in psychology? I was also wondering what happens to counselors when schools are closed for summer or winter break? I had that aspect in mind as well.
