For me, I love being involved in my kids education. I didn't have no where near the resources we have now. I love learning robotics, REALLY learning math (not just rote arithmetic), I hated history way back then but am now fascinated by it, love learning about art history, music etc...... my kids give me the avenue to pursue these interests that I might not have thought about it otherwise. Otherwise, I'd be spending my days in a research lab somewhere...but now, I'm enjoying passing on my passion for science to my kids and learning so many new things!
