I went to college. The last two years of college, I worked a semester (in my major) and went to school a semester. I learned very quickly that what you learn in class and in books is just a foundation for the real knowledge you learn once you are in the real world.
I would say that some of the most valuable information I learned were from people who didn't have a college education but had worked as a day to day laborer making all that "school" taught knowledge actually work.
I don't ever want to stop learning. There are so many things that I want to know about and learn to do.
