I’m very curious about your daily schedule. I was homeschooled for 12 years, 1 of 5 kids so I’m familiar with home education and having a hard time imagining how a single adult can both work and teach and take care 4 kids.
Most people must work during daytime hours, and formal learning (for example, math that pushes the boundary of what you know) does not work very well for kids (or adults in my experience) in the evening. I’m glad that you have the flexibility such that you don’t have to do work 8-to-6, but that’s clearly not realistic or even possible for most people.
How does one hard work their way out of this? Start a business so you can teach during the daytime and in the meantime your kids do what exactly?
