It takes time and practice. It takes courage. It takes a lot of things. It takes years and years of practicing the same thing over and over. It's about pain. It's about hurting. It's about bruising and bleeding. It takes a lot, which is why so few are able to join the Dark Class ninjas, where we have cookies.
Ninjas are silent, and deadly. Strike when necessary and never make the first move. Study the human body, know your weaknesses and the ones of others. when it comes time to strike only do so with the intent to kill. hesitation is weakness and hesitation can only cost you your life or someone elses. protect that which you love. and train like hell!!!! Study many combat arts until you find a style that suits you but continue to use them all. Love, hate, fear, and rage, these are the things that cause people the most pain, use that to your advantage. Turn yourself into a weapon as well as studying other weapons and finding one to master. Trust no one, question everything, this will keep you alive. start by learning how to walk quickly without making a noise in your footsteps. along with that listen to everything around you, learn to see without looking this is one of the most important points. disappear and only be seen by those who need to see you. I have learned this lesson the hard way and I know I am about to repeat myself, but anyone can snap at anytime, trust is a liability, Trust no one and question everything!
