At 15 I found myself at a full-contact karate class (Kyokushin). It's a type of martial arts, where you have to fight a lot, overcome pain and yourself. This taught me to accept challenges and always reach my goals.
When the time came to serve in the army, the prosecution was faster than the military. I was charged with assault. Stupid as we were, some guys and I robbed a person, and, of course, we were caught. It turned out ok for me, but in a couple years I got my suspended sentence for a robbery.
Then there were hard times, as many young men had back then. Sometimes I helped people get the money from their debtors, or, vice versa, helped get away from the extortion. Sometimes we would take the goods or the money and then forget to return. Not my proudest moments.
One time, I was almost stabbed to death because of some differences with another gang. Luckily, I stayed alive. And another time, I simply wasn't home when some armed dudes wanted to settle old scores.
One time I argued with a partner and he decided I've lived enough in this world. When I found out, I had to outplay him. I then had to deal with the Special Police Forces, wanting to charge me with attempted murder. It turned out ok, though. I'm free, the other one is alive.
