Are you considering it? I have never regretted it, although at times I have been tired. I have really pulled back toward a more "unschooling" type of schooling and we love it. We read, play, write and do some math. We do NOT do "public" school at home. I enjoy spending all day with my children, I really do! We do make lots of messes and it isn't perfect (we are all sinners) but I believe it is the way that things should be for us. Here is a good site for those considering homeschooling High School:
