Studying chemistry by correspondence presents unique challenges, not the last of which is the fact that I had to teach it to them.  They had considerably more enthusiasm about windsurfing and snorkeling than they did about chemistry.

By mutual agreement, we called this course Chemistry from Hell.  I dutifully went through the chemistry book with them page by page, and we worked through every problem at the end of each chapter.  It took four months of working four hours a day to finish the course and take the final exam.

I learned some valuable lessons when I taught chemistry to my children, but none of the lessons have anything to do with chemistry.  If you are thinking about teaching chemistry to your children, you should probably think again.  You can take a horse to water, but your can't make him drink.  We spent hundreds of hours standing in front of the water trough, but I'm not sure how much drinking got done.  I have given up teaching chemistry to my children.

But since you aren't my children, I have a small chemistry lesson I want to teach to you.  Fortunately, it's not Chemistry from Hell; it's only a few simple facts about the chemistry of your brain.

Whether you realize it or not, your brain chemistry has a massive impact on the direction and quality of you life.  Furthermore, you have a high degree of control over exactly what that chemistry will be.  You don't have to take a course in Chemistry from Hell to be able to run your mind and push your brain chemistry in a positive direction.
