Homeschooling mothers are not more patient, kind, maternal, or fun than any other mothers.
If you think homeschooling is important, you do it. When you slack off, you recognize it and work harder, just like you would in any other area of your life. No one is perfect, and you shouldn't expect yourself to be.
I have hardly any brain left.
Lists are helpful. Don't compare yourself to other homeschoolers. Just because they teach latin, art, and robotics doesn't mean you are failing your kids if you stick with math and reading.
Just jump in and do it for a year. See what you think.
You really can't mess them up in a year.
