I assume you do not know what a madhab is.
A madhab is a school of thought and a discipline of Islamic jurisprudence.
As a discipline the hanafi school of thought stresses personal responsibility.
I know very well what a Madhhab is. The Hanefi Madhhab was founded by Imam Abu Hanifa. It is based on his teachings which his students wrote down and then after his death his students continued explaining Islam and all new matters in the same manner and logic that he did and that he taught them. To this day, those who follow a Madhhab (which everyone should) they are following the opinions and views of the Scholars of that particular Madhhab.
We as laymen, are obligated to follow the Scholars, Allah comands it, so too his Prophet.
So your statements of not following anyone or any central leader or whatever, is wrong, contradicts your own statement of following the Hanefi Madhhab and contradicts the commands of Allah and his Messenger.
Even if you claim to not follow anyone without seeing the evidence for yourself, you still rely upon the writings of Scholars as you do not live at the time of the Prophet, that time is long gone. If your claim is that you study the hadith yourself on a matter then let me tell you that Muhammed never wrote any hadith, they were written down by the Sahaba and the Scholars that followed. So to say that you learn directly from the Sunnah is very incorrect. Even the hadith themselves are not all part of the Sunnah, there are contradictory hadith which are Sahih. And lastly, I am 110% sure that you are not an expert in the Arabic language. The commands of Allah (Qur'an) were not revealed in English, nor did our Prophet speak in English. To be able to derive rulings on your own as you say you need to be very well versed with the Arabic language to say the least.
