<human>: (I was advised to post this here as well.  Sorry if it's the wrong spot.)

I'm in a unique situation at the moment. I work at home and have a lot of free time once the work is done for the day. I don't have a lot of extra income, but I would like to learn a new skill or trade from home.

What would you suggest as far as a marketable skill -- something that I could eventually do to earn significant income?

I'm willing to treat learning this skill or trade like a second job. I am somewhat tech savvy, but not overly mathematical. I am not ready to go back to school for this new skill or trade, but if the payoff is there in the long-run I would consider it later down the line.

Could you distill the essence of the text into 1-3 sentences?
