When it comes to high-paying jobs, there is nothing like that. Any job can pay you huge amounts. It depends on the level you are operating. Also, the demands of each job largely depend on the level a person is operating on.
I have observed that high-paying jobs are less demanding and more flexible. That doesn't take anything away from the fact that every job requires diligence and hard work. I know of someone that is being paid huge amounts for just teaching diction part-time. Another person is teaching 4 subjects and is not getting a quarter of the previous guy's pay. The Bottomline is that everyone should work to improve themselves. Time and chance would happen to all of us.
