I have achieved many of my goals; others I never will. I hope to solve a few more of the little mysteries of life. Also, before I get too old to surive the hours involved, I would like to take on at least one more big project; something that consumes 110% of my attention for a year or two...or three. I tend towards something related to the up and coming hydrogen economy. https://www.physicsforums.com/showthread.php?s=&threadid=4127 I may also just stay focused on my business and having fun. What do you plan do be doing in ten, twenty, or even 50 years.
