Hahaha ok. I said lots of things about parenting before having kids too.
The fact that you're thinking about it is good but you're planning will be thrown away the day you become a parent.
There are far more important variables than age.
Homeschooling is a good idea. The education system is currently beginning a MAJOR reform and wont be the same in 10 years. Having a "bachelor's degree by 18" is flawed at its premise. The bachelor's degree itself means nothing even today, (I run a business and college degrees would mean a resume goes straight to the trash) as real world education and real world experiences are far more important and by the time your kids get to that age anyway the bachelor's degree system shant exist.
Those college kids are immature because their parents are retards and raised kids to send to send to college.
I wish you the best, and many happy years with a healthy family, but I would never suggest waiting past 30, even though I myself planned to not even consider kids until 32. Experience teaches a lot. I have dozens of peers. I know personally trying to start families at around 40 and most of them are relying on IVF because its LATE. The wealth they built, is now being BURNED on IVF.
