I like big brains and I can not lie.

I am trying to convince/show my kids that solving problems is cool. I talk alot about how big my brain is and how awesome it is to have a big brain and that the only way to get big brains is through hard work. Problem solving makes your brain get biggger and when you work out a tough problem you feel brain ache, but that is really just your brain becoming more powerful. When I asked the class how they felt after they had just worked through a problem P... raised her hand and said, "It feels like I am getting more smarter." The sentiment is there, but it definitely makes my brain ache too.
