Why could reading too many books be bad?

I was on reading sprint for last 18 months; finished 30 books; but slowly started to realise I was reading too much.
I realised after giving it few weeks of serious thought,
I was reading because I wanted to learn it all from other people's mistakes,
I was seeking to gain knowledge from other people's life's learning,
I was afraid to make mistake myself and learn.
I was cheating; uncounciously seeking to take short cut to wisdom.

What in them was a wisdom/knowledge/science, is in me(when I gain that knowledge from reading their books) but opiniatrety.
They had, along with conlusion, their journey to the truth but I had only the final result which is nothing but a part of knowledge.

reading from other people's books is like a borrowed wealth, like fairy money, though it were gold in the hand from which I received it, will be but leaves and dust when it comes to me.

This all makes sense, but I anyways am reading; I have, for now toned it down a little; cannot stop it entirely :)
