Looking back I wish

When I sit around doing whatever, I often wish that I had did many things differently.  I do not consider that I have not learned my way over the years, but I see so much out there that I wish I could be a part of it and build knowledge for my satisfaction.  I am sure that I am not the only one that feels this way, but for me, I want to be involved.  Why are China and other countries so much smarter than we are?  Should out school systems consider school curriculums that combine knowledge of many areas instead of social issues?  Maybe the next life I can look back and recall my shortcomings of this life and divest more in a better understanding of my abilities.
