How can I develop my language and writing?

Umm... My sister sinabi that I should read madami I think that would work.

Because I don't read much but I wirte alot

I agree with ripper :o i really never read anymore, but i write tons ! i have noticed since i stopped pagbaba my Pagsulat has gotten kinda sloppy and im having trouble putting what i want into words on paper. Now i have started pagbaba again and observing actual published works and the technique they use through out their writings. I helped me a lot. I even sometimes read artikulo and stories people post on fanpop XD.
Hope this helps! Keep writing!

Like the others said: pagbaba and seeing how real-life authors put their thoughts into words helps. Also, revision and planning ahead can really improve your quality of writing. Hope that helped. :)

i would read more....
i had the same problem and it worked for me
try it and then tagahanga me if it works in the susunod araw or so x
