I agree with what others have indicated. It's best to get a job with a steady paycheck - especially since the extra $ is so very important.
You have only been on etsy a short time and have not had many sales yet. Therefore, you cannot count on etsy for income any time soon. It certainly can be done - but it depends on so many things: what you are selling, how popular your items are, how much of a following do you have and do you get repeat customers, how many items are in your shop, how expensive and time consuming are your items are to make, which items are popular (and can you make more variations on the popular items), etc. You only learn about these things (and all of the etsy selling intricacies like optimum photos and SEO) after months and months of work. Do etsy in your spare time making/selling products you love. Hopefully in a year are two you will be sitting right where you want to be.
