We homeschooled all the way through.
I have three main pieces of advice.
1. Don't overthink it. Sometimes smart moms want to learn and do everything and they get really into reading all of the philosophies and looking at all the curriculums and it can lead to getting burned out before you even start.
2. Listen to your kids. If something isn't working, change it. That's the beauty of homeschooling.
3. Build your local support system of friends. Online information is great but there is no substitute for real friends when you need a shoulder to cry on or someone to watch the kids so you can go to the doctor alone.
