Prison Break - Always deal with the most important issue first. Michael Scofield has tons of problems and is constantly surrounded by chaos. Yet, he always focuses on the most pressing problem at hand and solves that first.
The Mentalist - Always think differently from the norm and have fun. Patrick Jane is quirky, eccentric and funny but never fails to show that he is the smartest guy in the room.
Burn Notice - Always have a Plan B. Michael Weston knows that in the field, anything can go wrong and is always prepared to deal with it.
Spartacus - Never give up fighting for what you believe in. Even when his woman dies or he has to kill his best friend, Spartacus, still fights for freedom.
Arrow - You can't do everything alone. Oliver Queen has good friends(JV partners?) to help him nail his targets.
Breaking Bad - Obsessing over your work or anything can make you lose everything. Things started to go haywire for Walter White, once he began obsessing over power and money.
The Walking Dead - Get far away from haters The survivors have to constantly kill or runaway from zombies which just wanna drag them down and eat them. Just like haters.
Dexter - Honestly... I learnt nothing but it's such a cool show
