Perfect murder

Part 2-Lessons

"Are you fucking kidding me? Danny, you are too fucking irresponsible! How the fuck did you decide it's a fantastic idea to dismember this fucking family! You are a fucking idiot!" he was yelling and then he just smacked the wall.
The shouting guy with visible anger management issues? Oh that's Eric. Not very tall or handsome, or athletic.. He is the nerd guy you were making fun of in gym class or was that just me..whatever.. He is my...co-worker... I guess. He is an IT specialist. Eric finds customers and sometimes gets me out of trouble. We split the payment 60% for me and 40% for him. It's fair. I am risking my ass, not he. Another fun fact, Eric's favourite word is "fuck". I know, no way you could have guessed it.
He was still shouting how stupid I am. I just put my headphones, I know I'm not smarty pants but ain't idiot maybe. I have to work out.
Lesson 1: Be physically strong
You cannot expect to commit crime and get away with it, if you have no strength. Run about 10miles(16km) a day, do about 30 push-ups, and some sit-ups and you should be just about right. And the obvious-have martial arts talent, manage guns and knives. Although, you can never be overprepared, so lift weights. If you are female, forget about having a womanly body. But who cares? If you feel beautiful, you are. Before this gets any cheesier, start working out if you want to be professional killer and you might survive long enough.
Lesson 2: Always be prepared
You don't know who and when might attack you. The easiest way? Just believe everyone wants to kill you. That way you either become psychotic paranoid bastard or a great self-defense tutor. Either is fine.
