I currently work as a independent contractor in Interventional Radiology Surgeries. I would really really like some direction as I want to move into working remotely and staying home/travel more...
I have been working online since last 2 decades and it has its pros and cons. As they say "The grass is always greener on the other side of the fence."
Anyway if you want to start out then there are plenty of opportunities. You should make a list of things that you would love to work on and once you have made up your mind on something specific, you could acquire knowledge for that subject with online courses and tutorials. (Because working from home gets boring real soon. But that is a whole new subject for the psychologists)
For example: I love programming and all so I went into web development. It also included designing and technically I could use Photoshop but I am not artistic with colors and drawing. There will be such things for sure in any line of work you choose where some things will be better than the other. Just choose wisely.
