pardon my English, eh..

i feel the urge to improve my English. all of sudden, i realise that i write and make all the grammatical mistakes without any intention of correcting them or at least checking for a smooth flow of reading. i'm really bad at constructing sentences and i think i have the tendency to add 'ing' at the end of verbs whenever i feel like it. this is really a problem. whose fault is this ha? i put my blame on my course, for not allowing me to write freely, creatively and enhance my writing skills, haha. wah, another added task to my already long list. help me with my English, friends. now i feel weird with my own writing.- grammatically 'concious' mind, for now that is.
