Good Paying, Socially Limited, Low Stress Jobs?

Hi I was wondering what are some high paying socially stress free or socially limited jobs. For instance from what I gather a computer programmer would be one type of job. My uncle is a computer programmer and it only recently occured to me he is an omnivert leaning more towards the introvert side. He also really likes computers. I live in Canada and am thinking about my future. I want to be in a career that suits my personality but at the same time gives me a decent wage. I have some serious problems with sleep. The problem is insomnia. I would really like a job that starts in the afternoon. For instance. There was a job I saw recently posted for a janitor for schools in the Toronto area. Now this job might not appeal to the majority of the population. It however struck a chord with me. The jos starts at $15.53/hr Canadian (not bad at all) and the shift starts at 3pm. This is the perfect time for me to start work. Why because if I stay up all night tossing and turnning I'll still have some time to sleep in. So here's what I'm getting at. The rules for replying to this post are as follows.

1. Name a high-paying socially stress free job.
2. Name the amount of time needed to invest in the education
to get this job. The shorter the better.
