What is your reason of starting nofap?

Emmm....I just wanna to get rid of being controlled by the porn. As a result of watching so many porn, sexy fantasy often break into my mind and interrupt my thought. Sometimes it can be worse if it mislead my life, it will make me wanna commit a crime, like rape etc. But I dont wanna hurt others, also I cannt get rid of them. This two things make me painful. Then I will feel guilty which depressed me. This is the first reason. But still this reason is not strong enough to help me hold on.
whta really helps me detemined to Nofap is the science that told me the porn is a cheat, which make use of my brain's flaw to cheat me. this makes me really angry. I cant stand this, and this times I decide whatever I'll make it (Nofap) to the end.
Just explain it clearly. What the brain's flaw means is that our brain just cannt distinguish the porn and really sex. When the brain watch porn it just think it is in sex. But it's not the truth. Same feelings, different results. we are happy in sex because our brain wants us to keep connected with others, and then enjoy love. But porn just take away everything. After watching porn I dont want talk with girls, I become lazy, and fatally I lose the meaning of life. All of this just because the cheater.
So I decided to fight back. Sometimes the urge really makes painful. But I know I am keep going, and I am taking back what I have lost in past.
But actually, I am not always being rational like this, sometimes I may just forget my reasons, just like the state before I watch this thread, so thank you I just pick it up. And you may want to ask what supported me to fight against urge or something like that. It is failure. Every time I fail, I will be hurted by the faliure. But I am not only be frustrated, I get more angry. And throngh I relapsed, I just decrease the frequency of watching porn, which makes the urge weaker. With my angry power, I first time win in the head-on confrontation with urge(though in that time I fainted finally as I used up all my energy, hahhh ). And after that victory, I feel the urge become controllable, in spite, it is still strong.
By the way, I want end this comment with some thoughts about urge.In past, I just thought that the urge can be one of motivations of life. So sometimes I just be relent. But it fails me so many times, so I understand there must be something wrong.And now I can tell that the urge has been polluted by the porn, which means one of my life function has been injured, to restore it I must finish my reboot，which now is all I want.
