The best homeschooling (and parenting)(and life) advice I ever received was that God knows what our purpose is, what our calling in life will be. And we are created perfectly to suit that calling. We are equipped/hardwired for the job we're meant for. To me that means (you know, just off the top of my head) that a child whose tears are mixed with pencil lead while doing math problems, and who writes notes such as this one, isn't meant to be a mathematician. And that's okay.
Every kid (and grownup!) needs to find his or her niche. A place to shine. Music and performing (and nature) are my son's. Here's a video of Nature Boy performing a solo in his most recent musical. (Note: If you have an email subscription, the video might not appear in the email. Not sure why.)
