He sort of has a point. There are only 3 ways to get better at writing.
I assume you mean Fiction, btw
The first is writing. Alot.
The second is planning everything out and tweaking everything perfectly and even then you STILL need to have a good basic writing skill.
The third is by writing lots of short stories which constantly change narrative style, pace, tone, themes, motifs, etc so as to extend your range. Although this isn't suggested if you want to go into one specific genre. (Please don't be a fantasty-fag teen writer. We're looking at you, Mr.I-wrote-Eragon-at-16.)
P.S: If you try and improve your writing, it's most likely you lack the talent to write. Thus either do what I said which is all personal discovery stuff or take proper writing courses.
..Which still require talent. So, it seems you might be fucked OP. ;D
