If teaching doesn’t work out IT/ computer

I’m going into a teaching program well “internship” and the work is stressful I already know but this is to find out if I like it...if I don’t I’ve been looking into IT related fields. My friend has found success in the computer science field with only a certification didn’t finish school because of the huge amount of money a job offered. That’s my plan c basically. I wish I could turn around and re do my life to get a bachelors in something with more opportunities
