Just before he died at age 86, I asked my dad if he had any regrets. He said no regrets, but, he said, "there is still so much to learn".
As Tom said, even with his experience and age, he learns something new every day. That is why I monitor this list, GPI, and PTI, keep attending chapter meetings, go to as many seminars as possible, and attend the Annual Convention every year.
Yes, thank you, Tom, and everyone else for sharing your knowledge and experience. I've still got so much more to learn.
