This is great! The board wisdom is on a roll today.
We chose discipline of the mind as the priority: learning to attack problems and see them through until solved. When she is allowed to avoid, she loses confidence in her abilities and of course gets nothing done. So, our first goal of homeschooling is to learn how to follow through on her dreams with a practical plan. And that naturally means she needs to push herself. So the academics, as well as other life areas will come with it. Social comes after that with this reasoning: When she is confident in herself and who she is, she is in better shape to find true friends.
