I was one of those students who went to a public school which the standard of education was pretty darn low. When I got to college I was hit hard with just how behind I was. Many students were far above me all around.
When I graduated HS around 98% of students went off to colleges of some kind. Now when I look at facebook at least of the people I knew only a handful actually has a real job and of those people they are the ones who finished college. The rest don't have careers.
For me and the few others college fixed us. It forced us to do the work and work our way up to what most people are capable of.
So when you hear about the all star developer who never went to college and is doing great. Be sure of one thing, that person got a great education and good problem solving skills were learned. For the rest of us who never got this, you need to make up for it somehow. College is your shot.
