Research. Get comfortable. Relax. Play. Don't spend a ton of money, especially the first year you decide to go for it. Remember that everything that children learn gets relearned at least 1 more time in more depth 5 years on, and typically several times. (Even something as basic as the alphabet; orally, visually, writitng, cursive, & typing... but definitely things like Ancient Greek History). Look into philosophies. Realize that philosophies can change. Have a "stock" (but heartfelt) answer to the common questions / people trying to ask an intelligent question (but it's the same ones everyone asks... two of mine, just for example, is nothing more than the honest truth when people say "I could never _____" which is "Homeschooling is easy, it's parenting that's hard." &/or "What matters is that a child is in school and learning, I don't care whether that's public, private, boarding, or homeschool... every family with caring parents knows what best for themselves and their own kids, ya know?"). Ignore the extremists (extremists exist in every subculture... in HS'ing it tends to be the radical unschoolers on one side and the extreme & or fundamentalist christians on the other side... BOTH are very different from the kick butt unschoolers and christian HS'ers... and both are the minority, but they're loud minorities). Have fun. ENJOY childhood... it's so very very brief. Get connected IRL or online (or preferably both) to other HS'ers. Realize that some will drive you insane. Just because you choose the same schooling method doesn't mean you're actually going to like each other. Imagine a standard PTA, does everyone like each other? Nope. So don't feel obligated to school like anyone else or like the individuals you meet in one specific place. Don't close the door on awayschoolers, or you can miss out on some amazing friends and parents.
My hands down top 5 favorite "starting out" / continuing resources are
