Getting job as substitute teacher in Life of a cat mom

Years ago I wanted to become a school teacher but I couldn’t pass the praxis. I graduated with an RBA but couldn’t pass the test to become a teacher. I packed my bags and came home in 2013. Now I work at a hotel serving breakfast not making enough money to survive. I have been talking to my husband about trying to get a job as a substitute teacher. I would choose when I worked and when I didn’t and I would get $150 dollars a day. Sounds a lot better than serving entitled people at a hotel.
