Reading and not writing makes Amna a dull girl

I have been reading a lot of blogs, articles, stories here and there. I have been always fond of reading. I used to get used books from old book banks and then exchange them for more books after reading them. I have been very good at essay writing and stuff, i even used to write my own speeches for school competitions... But now i feel a lack of writing power.. i feel i don`t write as much as i should or want to.. i have so much to write about but the lazy me refuses to sit and write something good.
What is the remedy ????
