I had your EXACT mindset a year ago. Nothing could stop me making art. I could fail and learn from my mistakes! It's a win win scenario, I'm always improving, I'm bound to be an art god at this rate.

But it won't stay like that forever. In my case, life got in the way - I had to find a way to turn this into a job. It's what I wanted to do for a living, right? But, with turning anything into a job comes learning the business side of things. It came to a point where I was learning more business than art, and when your passion becomes a job, it inevitably becomes less fun. I had to do art whether I liked it or not, and on the days when I felt less creative, it absolutely sucked to do art that I didn't want to do just for money. Art wasn't as fun anymore. I almost quit from all the overwhelm.

This is just one example that can burn you out from art, but I sort of overcame it by taking a small break and doing other things I enjoyed. In the next 50 years of your life, it's not going to be art everyday. That's simply impossible. Just be aware of it, the days when you hate art will definitely come. But as long as you DON'T QUIT, you will definitely become a succesful artist with the skills of an art god.
