The moments that change your life can be as small as a chat by a friend's locker or as big as a car accident.
When I was 17 I left school with no degree, no money and no idea what to do with my life. My dad managed to get me job in retail and on my way to work (first day) I got hit by a car.
The manager didn't give a f*ck and gave my position to someone else. With literally nothing left to do I decided to go back to school. That was about 7 years ago. I finished school with honors, went to university, got my bachelors degree in electrical engineering (something everyone I knew and talked to told me was impossible for a f*ck up like me) and now I work as an engineer making more money in my first year of work than I ever did in my entire life.
Sometimes I think about tracking the guy down who hit me with his car to thank him.
