When I was sent to prison at the age of 21. A very tough experience. I went from screwing around with no direction in life, partying, etc. to a complete survival mode mindset. I had to grow up fast, or at least, take things a lot more seriously. When I got out several years later on parole, I was a completely different person. I had no intention of ever going back, so settled into a job and stable existence. Not an easy journey, but lots of good lessons along the way.
