Lots of JETs finish and then go to grad school.
I couldn't go back to school. I did fine in college but it was hell. Lots of money and I never felt like it was worth it. I learned things but it always felt so... forced.
Anyway, I took an online course about Machine Learning. It was about three to five hours a week and I got a hand on a new skill. Who knows if I'll ever use it in the future. But I learned something. And I have "proof" of it. Hooray!
I could take another course, but it's summer vacation. I need a little break. I think I might play me some Dragon Quest 11.
