Your True Goal
If you are the type of artist who wants to go full-time, you have to put your heart to it. Though it may seem to be a good idea and mindset, if earning is your primary goal, there are a lot of easier ways. Indeed, making money out of your art will kill your creativity. If you only do your artwork as a part of a chore, it is not exciting anymore. Take note that being a full-time artist needs a lot of commitment and is not always easy.
