Challenging myself

First of all I will try to write the best way i can in English , since my natural language is Portuguese .

Second I have now 10 days without watching or have a masturbation , so that is as low step , however its have been difficult and stressing this days , I am not a stressed person but this days seems to be the hell . Its have been a long time since I don´t feel that way so stressed , sometimes I feel just like I need to punch someone just to calm down , of course I didn´t do it .

Third , I have 19 years and I study Biology in Brazil , this is important to say because every day I study natural things , and quitting pornography is for me a experiment , but in this case with my self , witch is more exciting .

I would like to say that I have tried this challenge sometimes , and my long journey was 30 days . Now , I can´t remember the benefits of that journey because i was on vacation time . That is it for the first day here !
