Whats a good job for a shy person?

Any office position that's behind the scenes (mail room, photocopy person, e.t.c.)

Make cartoons for youtube. You dont need to interact with anyone. Just make sure its really good. Though that does sound kinda lonely. Become a writer. Submit short stories to online magazines. But if you want to make any real money youll have to write a novel which youll have to promote on tour. Computer programmer. Make a bada$$ app that everyone is willing to pay for. Hope this helps. Its really hard being shy but l you may have to settle for a job that isnt so kind to shy people like I did just to pay the bills and eat. Im training at a car audioshop.

Pretty much anything with computers (data entry, IT, computer programming, graphic design) would be good. Also: accounting, warehouse, janitorial...

research unless you want to maybe become a little unshy?

Busboy or any other jobs where there is minimal contact with other people. It would be good for you to overcome this though, I used to be extremely shy only a few years ago.
