I have a friend, also a high school classmate, and we get along pretty well.

He studied nursing and is very honest, but he’s quite reserved.
Right after graduation, I suggested he switch industries. He’s a medical student and completed internships faster than us, even working paid positions without salary.
Now he works overtime every day at the hospital, exhausted and working hard, earning just over 3,000 yuan a month.
He previously tried selling on Xianyu and setting up a street stall, but didn’t make any money.
What would happen if I now encouraged him to focus entirely on learning AI?
