Does a degree define success? No.
What you produce, for other people can either make you successful, or not.
Attending college does help to push you somewhere in life, but what colleges don't do is give you a job. Because this is something that you have to earn on your own.
I managed to get an interesting job a long time ago. I don't know if a degree was needed to be able to do the job. I worked hard on my own to be able to do the job, and I also sold myself.
Yes, I have a college education, but I don't have any degrees. I studied a lot on my own after graduating from college, so that's how I was able to do the job that I got a long time ago.
