I'm a teacher. I've been creating digital materials as a side gig for three years, and last year my side income exceeded my salary.
I'm not posting this to brag. I quit this same gig twice before, and I want to explain why, in case it helps someone.
I quit for the first time in the sixth month. It wasn't about the money; it was burnout. School in the morning, computer in the evening. I was exhausted after three months.
I quit for the second time a year later. This time it was shame. Sounds weird, but that's how it was. People around me made comments like "Isn't teaching enough?" and it got to me.
When I started for the third time, I changed two things. Two evenings a week and Saturday mornings — that's it, no more. And I didn't tell anyone except my spouse.
It went like that for two years. Now I do it full-time, but I didn't leave school immediately. I waited another year until my income became stable.
