Re: Looking for some job ideas
What about accounting? Do you like numbers?
You could do photography but maybe something more routine, like business photography. Real Estate photography/ staging, internet sales photography (ebay), ect might be a good fit since it requires less interaction with people. Sports photography is another thing that would allow you to sit back and observe. (I am a freelance photographer and have done all these things to make money)
Another idea might be to enroll in some professional development courses on communication or join some professional organizations to meet others. Just because you are a natural introvert doesn't mean that you shouldn't work on developing your people skills. Just enhancing those skills and getting comfortable with working with others will open doors in your career.
You can do anything you want to put the work in to! Good luck to you!!
