You can also pursue the CPA designation for a year (it is a hard test), and alter the outcome of all your future jobs, particularly as you age. That extra income can result in writing/drawing seminars, money in the bank, working part time and getting paid a higher hourly rate so you can work on that book and draw that painting, you also will be able to tutor and teach others which is a great career path change as you age. The idea that you won’t draw and write if you make a living doing something else, is just not true. It just may be a slower process
