I am unemployed right now. I have been trying to learn TA for a couple of months now. To be honest it is really really hard. Even though I studies engineering, experience is really important than theories. All I can say is, it is better to try to learn TA and understand the market (read all about cryptos, projects, and see the future) while you are not working.
I am also a tattoo artist, I will go back tattooing ASAP and continue learning TA.
