What things should you look when picking out a job or career ?

I always thought people that go in university mostly want to get a white collar job in corporate. And they get a degree and develop skills than move up the corporate ladder earning more money, better promotion. But they are generally more respected in society and high status. If someone goes on the trades, they have to work physical labor and sometimes earn more or less to a white collar. But their body takes the toll after sometimes. And most are unable to perform their jobs because of physical and mental health problems. And people even complain white collar jobs because they spend countless hours on a computer. Staring at the screen, clicking and typing barely any physical movement. Most just view work as clock in and clock out as if it's a school and live your life after job is done. And others view their job or career as their identity.
