You are most generous!

My dad (23 patents!) always wanted us (3 sons) to persue science. He was, for years, disappointed at the non-science direction that 2 of the sons followed. I was the science son, became a meteorologist. It was special to see how, over the years, he found himself proud of the achievements of his non-science sons.

It sounds as if your sons and daughters will feel your pride all along the way!
